Stauffer Chemical
Stauffer Chemical Company was an American chemical company which manufactured herbicides and pesticides for various agricultural crops. It was acquired by Imperial Chemical Industries from Chesebrough-Pond's Inc. in 1987. In 1987, Stauffer's head office was in Westport, Connecticut. Late that year, Imperial sold Stauffer's basic chemicals business to Rhône-Poulenc S.A. History The company was founded in 1885 in San Francisco as a partnership between two young Europeans; a German, John Stauffer Sr., and a Frenchman, Christian de Guigne. Ships exporting wheat to Europe used stone from the chalk cliffs of Dover as ballast. This discarded ballast became the inexpensive raw material for the newly formed company. The company was incorporated by John Stauffer Sr., who died on March 4, 1940, at the age of 78. In 1931, the company announced plans for a new manufacturing subsidiary, the Pacific Hard Rubber Company. Hans Stauffer, nephew of founder John Stauffer Sr, who joined his unc ...

Chemical Companies Of The United States
A chemical substance is a form of matter having constant chemical composition and characteristic properties. Some references add that chemical substance cannot be separated into its constituent elements by physical separation methods, i.e., without breaking chemical bonds. Chemical substances can be simple substances (substances consisting of a single chemical element), chemical compounds, or alloys. Chemical substances are often called 'pure' to set them apart from mixtures. A common example of a chemical substance is pure water; it has the same properties and the same ratio of hydrogen to oxygen whether it is isolated from a river or made in a laboratory. Other chemical substances commonly encountered in pure form are diamond (carbon), gold, table salt (sodium chloride) and refined sugar (sucrose). However, in practice, no substance is entirely pure, and chemical purity is specified according to the intended use of the chemical. Chemical substances exist as solids, liquids, ...

Chemical Industry
The chemical industry comprises the companies that produce industrial chemicals. Central to the modern world economy, it converts raw materials (oil, natural gas, air, water, metals, and minerals) into more than 70,000 different products. The plastics industry contains some overlap, as some chemical companies produce plastics as well as chemicals. Various professionals are involved in the chemical industry including chemical engineers, chemists and lab technicians. History Although chemicals were made and used throughout history, the birth of the heavy chemical industry (production of chemicals in large quantities for a variety of uses) coincided with the beginnings of the Industrial Revolution. Industrial Revolution One of the first chemicals to be produced in large amounts through industrial processes was sulfuric acid. In 1736 pharmacist Joshua Ward developed a process for its production that involved heating saltpeter, allowing the sulfur to oxidize and combine with water ...

Phosphorus Trichloride
Phosphorus trichloride is an inorganic compound with the chemical formula PCl3. A colorless liquid when pure, it is an important industrial chemical, being used for the manufacture of phosphites and other organophosphorus compounds. It is toxic and reacts readily with water to release hydrogen chloride. History Phosphorus trichloride was first prepared in 1808 by the French chemists Joseph Louis Gay-Lussac and Louis Jacques Thénard by heating calomel (Hg2Cl2) with phosphorus. Later during the same year, the English chemist Humphry Davy produced phosphorus trichloride by burning phosphorus in chlorine gas. Preparation World production exceeds one-third of a million tonnes. Phosphorus trichloride is prepared industrially by the reaction of chlorine with white phosphorus, using phosphorus trichloride as the solvent. In this continuous process PCl3 is removed as it is formed in order to avoid the formation of PCl5. :P4 + 6 Cl2 → 4 PCl3 Structure and spectroscopy It has a trig ...
