Pecten

There are two main processes for the synthesis of ethyl alcohol from ethylene. The eadiest to be developed (in 1930 by Union Carbide Corp.) was the indirect hydration process, variously called the strong sulfuric acid—ethylene process, the ethyl sulfate process, the esterification—hydrolysis process, or the sulfation—hydrolysis process. This process is stiU in use in Russia. The other synthesis process, designed to eliminate the use of sulfuric acid and which, since the early 1970s, has completely supplanted the old sulfuric acid process in the United States, is the direct hydration process. This process, the catalytic vapor-phase hydration of ethylene, is now practiced by only three U.S. companies Union Carbide Corp. (UCC), Quantum Chemical Corp., and Eastman Chemical Co. (a Division of Eastman Kodak Co.). UCC imports cmde industrial ethanol, CIE, from SADAF (the joint venture of SABIC and Pecten [Shell]) in Saudi Arabia, and refines it to industrial grade.

Cawe (Pachycereus pecten-aboriginum) is yet another species of hallucinogenic cactus, which grows in Mexico. It is also a columnar cactus, growing up to 35 feet in height. It is known as Cawe or Wichowaka to the Tarahumara. Studies have identfied 4-hydroxy-3-methoxyphenylethylamine and 4-tetrahydroisoquinoline alkaloids as the probable psychoactive constituents.

Consider chemistry. What are isoquinolines These are chemical structures built around a two-ring compound. This compound, Isoquinoline, consists of a benzene ring and pyridine ring fused together at a specific bond. There is a pattern of substitution that gives an isoquinoline its absolute definition. Thus, for example, Salsoline is an isoquinoline, which is a major component of the Pachycereus pecten-aboriginum plant.
