Environment glycol

In the chemical industry, titanium is used in heat-exchanger tubing for salt production, in the production of ethylene glycol, ethylene oxide, propylene oxide, and terephthaHc acid, and in industrial wastewater treatment. Titanium is used in environments of aqueous chloride salts, eg, ZnCl2, NH4CI, CaCl2, and MgCl2 chlorine gas chlorinated hydrocarbons and nitric acid. [Pg.110]

NOTE Glycol selection should also take into account the risk of leaks to the environment and the ultimate safe disposal of the material. Propylene glycol is a safer alternative to ethylene glycol because of its very low mammalian toxicity. [Pg.177]

Any discussion of the prebiotic phosphorylation of nucleosides must take into account the probably neutral or alkaline conditions in a prebiotic environment. Some model phosphorylating systems have been studied, for example, the synthesis of /S-o-ribofuranose 1-phosphate from ribose and inorganic phosphate in the presence of cyanogen. Sodium trimetaphosphate will phosphorylate cw-glycols in good yield under alkaline... [Pg.123]
