Ethylvanillin
Ethylvanillin is the organic compound with the formula (C2H5O)(HO)C6H3CHO. This colorless solid consists of a benzene ring with hydroxyl, ethoxy, and formyl groups on the 4, 3, and 1 positions, respectively. It is a homologue of vanillin, differing on the 3 position. Preparation Ethylvanillin is prepared from catechol, beginning with ethylation to give guaethol (1). This ether condenses with glyoxylic acid to give the corresponding mandelic acid derivative (2), which by oxidation (3) and decarboxylation, gives ethylvanillin (4).Karl-Georg Fahlbusch, Franz-Josef Hammerschmidt, Johannes Panten, Wilhelm Pickenhagen, Dietmar Schatkowski, Kurt Bauer, Dorothea Garbe, Horst Surburg "Flavors and Fragrances" in Ullmann's Encyclopedia of Industrial Chemistry, Wiley-VCH, Weinheim: 2002.

Vanillin
Vanillin is an organic compound with the molecular formula . It is a phenolic aldehyde. Its functional groups include aldehyde, hydroxyl, and ether. It is the primary component of the extract of the vanilla bean. Synthetic vanillin is now used more often than natural vanilla extract as a flavoring in foods, beverages, and pharmaceuticals. Vanillin and ethylvanillin are used by the food industry; ethylvanillin is more expensive, but has a stronger note. It differs from vanillin by having an ethoxy group (−O−CH2CH3) instead of a methoxy group (−O−CH3). Natural vanilla extract is a mixture of several hundred different compounds in addition to vanillin. Artificial vanilla flavoring is often a solution of pure vanillin, usually of synthetic origin. Because of the scarcity and expense of natural vanilla extract, synthetic preparation of its predominant component has long been of interest. The first commercial synthesis of vanillin began with the more readily available na ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shalimar (perfume)
Shalimar is a perfume originally created by Jacques Guerlain in 1921 for French perfume and cosmetics house Guerlain. In production continuously since 1925, Shalimar is currently a flagship product for Guerlain. History Shalimar was created by perfumer Jacques Guerlain in 1921, but after another company claimed to already have a fragrance by the same name, Guerlain was forced to rename the fragrance "No. 90" until a legal dispute over the name was settled. Shalimar was re-released in 1925 at the International Exposition of Modern Industrial and Decorative Arts. Jacques Guerlain was inspired by Mumtaz Mahal, the wife of Shah Jahan, Mughal emperor of India, and for whom the Taj Mahal in Agra and the Shalimar Gardens in Lahore were built. The harmony of Shalimar was created when Jacques Guerlain poured a bottle of ethylvanillin into a bottle of Jicky, a fragrance created by Guerlain in 1889. Raymond Guerlain designed the bottle for Shalimar, which was modeled after the basins o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jicky
Jicky is a perfume originally created by Aimé Guerlain in 1889 for French perfume and cosmetics house Guerlain. Introduced in 1889, it is the oldest continuously-produced perfume in the world. History Jicky was one of the first perfumes created with the addition of synthetic materials, and was the first abstract perfume in history, meaning it is not based on a single note. Its perfume notes include: spice, lemon, lavender, wood and vanilla. Its stopper is shaped like a champagne cork. Jicky was the nickname of Aimé Guerlain's nephew, Jacques Guerlain, and according to legend, was also the pet name of Aimé's girlfriend from his time studying in England.

Catechol
Catechol ( or ), also known as pyrocatechol or 1,2-dihydroxybenzene, is a toxic organic compound with the molecular formula . It is the ''ortho'' isomer of the three isomeric benzenediols. This colorless compound occurs naturally in trace amounts. It was first discovered by destructive distillation of the plant extract catechin. About 20,000 tonnes of catechol are now synthetically produced annually as a commodity organic chemical, mainly as a precursor to pesticides, flavors, and fragrances. Catechol occurs as feathery white crystals that are very rapidly soluble in water. Isolation and synthesis Catechol was first isolated in 1839 by Edgar Hugo Emil Reinsch (1809–1884) by distilling it from the solid tannic preparation catechin, which is the residuum of catechu, the boiled or concentrated juice of ''Mimosa catechu'' (''Acacia catechu''). Upon heating catechin above its decomposition point, a substance that Reinsch first named ''Brenz-Katechusäure'' (burned catechu acid) ...

Organic Compound
In chemistry, organic compounds are generally any chemical compounds that contain carbon-hydrogen or carbon-carbon bonds. Due to carbon's ability to catenate (form chains with other carbon atoms), millions of organic compounds are known. The study of the properties, reactions, and syntheses of organic compounds comprise the discipline known as organic chemistry. For historical reasons, a few classes of carbon-containing compounds (e.g., carbonate salts and cyanide salts), along with a few other exceptions (e.g., carbon dioxide, hydrogen cyanide), are not classified as organic compounds and are considered inorganic. Other than those just named, little consensus exists among chemists on precisely which carbon-containing compounds are excluded, making any rigorous definition of an organic compound elusive. Although organic compounds make up only a small percentage of Earth's crust, they are of central importance because all known life is based on organic compounds. Living t ...

Phenol Ethers
Phenol (also called carbolic acid) is an aromatic organic compound with the molecular formula . It is a white crystalline solid that is volatile. The molecule consists of a phenyl group () bonded to a hydroxy group (). Mildly acidic, it requires careful handling because it can cause chemical burns. Phenol was first extracted from coal tar, but today is produced on a large scale (about 7 billion kg/year) from petroleum-derived feedstocks. It is an important industrial commodity as a precursor to many materials and useful compounds. It is primarily used to synthesize plastics and related materials. Phenol and its chemical derivatives are essential for production of polycarbonates, epoxies, Bakelite, nylon, detergents, herbicides such as phenoxy herbicides, and numerous pharmaceutical drugs. Properties Phenol is an organic compound appreciably soluble in water, with about 84.2 g dissolving in 1000 mL (0.895 M). Homogeneous mixtures of phenol and water at phenol to ...

Olfactory Art
Olfactory art is an art form that uses scents as a medium. Olfactory art includes perfume as well as other applications of scent. The art form has been a recognized genre since at least 1980. Marcel Duchamp was one of the first artists who pioneered with using scents in art.Ashraf OsmanHistorical Overview of Olfactory Art in the 20th Century, 2013 Examples of olfactory art In 1938, the poet Benjamin Péret roasted coffee behind screens at the Exposition Internationale du Surréalisme which was orchestrated by Marcel Duchamp, and was possibly one of the first true examples of olfactory art. (from the book "Salon to Biennial - Exhibitions that Made Art History", Volume 1: 1863-1959 Hardcover – July 2, 2008 by Bruce Altshuler) A series of chess sets where the pieces could be distinguished only by scent were made by Takako Saito in 1965. ''Spice Chess'' and ''Smell Chess'' relied on the use of spices or scented liquids in the pieces. In ''Spice Chess'', the black king was sc ...

Chocolate
Chocolate is a food made from roasted and ground cacao seed kernels that is available as a liquid, solid, or paste, either on its own or as a flavoring agent in other foods. Cacao has been consumed in some form since at least the Olmec civilization (19th-11th century BCE), and the majority of Mesoamerican people ─ including the Maya and Aztecs ─ made chocolate beverages. The seeds of the cacao tree have an intense bitter taste and must be fermented to develop the flavor. After fermentation, the seeds are dried, cleaned, and roasted. The shell is removed to produce cocoa nibs, which are then ground to cocoa mass, unadulterated chocolate in rough form. Once the cocoa mass is liquefied by heating, it is called chocolate liquor. The liquor may also be cooled and processed into its two components: cocoa solids and cocoa butter. Baking chocolate, also called bitter chocolate, contains cocoa solids and cocoa butter in varying proportions, without any added sugar. Powder ...

Chemical Formula
In chemistry, a chemical formula is a way of presenting information about the chemical proportions of atoms that constitute a particular chemical compound or molecule, using chemical element symbols, numbers, and sometimes also other symbols, such as parentheses, dashes, brackets, commas and ''plus'' (+) and ''minus'' (−) signs. These are limited to a single typographic line of symbols, which may include Subscript and superscript, subscripts and superscripts. A chemical formula is not a chemical nomenclature, chemical name, and it contains no words. Although a chemical formula may imply certain simple chemical structures, it is not the same as a full chemical structural formula. Chemical formulae can fully specify the structure of only the simplest of molecules and chemical substances, and are generally more limited in power than chemical names and structural formulae. The simplest types of chemical formulae are called ''empirical formulae'', which use letters and numbers ind ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
