1,2-Dioxane

	1,2-Dioxane 1,2-Dioxane or ''o''-dioxane is an organic compound with the molecular formula (CH)O, classified as a cyclic peroxide. Its synthesis was reported in 1956 by Criegee and Müller, who prepared it by reacting butane-1,4-diol bis(methanesulfonate) with hydrogen peroxide Hydrogen peroxide is a chemical compound with the formula . In its pure form, it is a very pale blue liquid that is slightly more viscosity, viscous than Properties of water, water. It is used as an oxidizer, bleaching agent, and antiseptic, usua ... and distilled it as a colorless liquid. Acids and bases decompose it to ''gamma''-hydroxybutyraldehyde.

	1,3-Dioxane 1,3-Dioxane or ''m''-dioxane is an organic compound with the molecular formula . It is a saturated six-membered heterocycle with two oxygen atoms in place of carbon atoms at the 1- and 3- positions. 1,4-Dioxane, which is of greater commercial value, is an isomer. Both dioxanes are colorless liquids. Preparation and derivatives The parent 1,3-dioxane is prepared by the reaction of formaldehyde and 1,3-propanediol in the presence of Brönsted or Lewis acid catalysts. Substituted derivatives can be used as protecting groups for carbonyl compounds. are prepared from the reaction between a ketone or an aldehyde with 1,3-diols. They can also be produced by the Prins reaction The Prins reaction is an organic reaction consisting of an electrophilic addition of an aldehyde or ketone to an alkene or alkyne followed by capture of a nucleophile or elimination of an H+ ion.

	Organic Compound Some chemical authorities define an organic compound as a chemical compound that contains a carbon–hydrogen or carbon–carbon bond; others consider an organic compound to be any chemical compound that contains carbon. For example, carbon-containing compounds such as alkanes (e.g. methane ) and its derivatives are universally considered organic, but many others are sometimes considered inorganic, such as certain compounds of carbon with nitrogen and oxygen (e.g. cyanide ion , hydrogen cyanide , chloroformic acid , carbon dioxide , and carbonate ion ). 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, and even ...

picture info	Peroxide In chemistry, peroxides are a group of Chemical compound, compounds with the structure , where the R's represent a radical (a portion of a complete molecule; not necessarily a free radical) and O's are single oxygen atoms. Oxygen atoms are joined to each other and to adjacent elements through Single bond, single covalent bonds, denoted by dashes or lines. The group in a peroxide is often called the peroxide group, though some nomenclature discrepancies exist. This linkage is recognized as a common polyatomic ion, and exists in many molecules. General structure The characteristic structure of any regular peroxide is the oxygen–oxygen covalent single bond, which connects the two main atoms together. In the event that the molecule has no chemical Substituent, substituents, the peroxide group will have a [−2] Formal charge, net charge. Each oxygen atom has a charge of negative one, as 5 of its Valence electron, valence electrons remain in the outermost Atomic orbital, orbital ...

	Rudolf Criegee Rudolf Criegee (23 May 1902 — 7 November 1975) was a German organic chemist. Early life Criegee was born on 23 May 1902 in Düsseldorf to a wealthy family. His father worked as a court director. The family was national liberal, Prussian and Protestant, managing what Rudolf Criegee felt was a great fortune. His happy childhood was ended by the World War I. In March 1915, his eldest brother died on the Western Front, while a second brother was seriously injured in the summer of 1916. Criegee himself was drafted. After the post-war period, he matriculated at the University of Tübingen in chemistry in 1920. After four semesters of study and moderate success, his experience in student fraternity Germania and twelve duels, Criegee changed to the University of Greifswald. He remained there for three semesters and passed his first examination. He moved to the University of Würzburg and received his PhD in December 1925 at Otto Dimroth with a thesis on acridinium salts.

picture info	Hydrogen Peroxide Hydrogen peroxide is a chemical compound with the formula . In its pure form, it is a very pale blue liquid that is slightly more viscosity, viscous than Properties of water, water. It is used as an oxidizer, bleaching agent, and antiseptic, usually as a dilute solution (3%–6% by weight) in water for consumer use and in higher concentrations for industrial use. Concentrated hydrogen peroxide, or "high-test peroxide", decomposes explosively when heated and has been used as both a monopropellant and an oxidizer in rocketry. Hydrogen peroxide is a reactive oxygen species and the simplest peroxide, a compound having an oxygen–oxygen single bond. It decomposes slowly into water and elemental oxygen when exposed to light, and rapidly in the presence of organic or reactive compounds. It is typically stored with a Stabilizer (chemistry), stabilizer in a weakly acidic solution in an opaque bottle. Hydrogen peroxide is found in biological systems including the human body.
