Chlorhydrine

Fumigation with ethylene oxide does indeed lead to a considerable reduction in the germ count (and at the same time destruction of insects), but the process, because of the formation of toxic reaction products (ethylene chlorhydrin, ethylene glycol) has been banned throughout the European Community since 01.01.1990 Ionizing irradiation a declaration of the treatment is obligatory, but such drugs find little acceptance by the public who expect nature s products as such. [Pg.35]

Epichlorhydrin.—It is a noteworthy fact that althoug-h hydiochloric acid can leplace hydroxyl by chlorine in the case of the monohydric alcohols, the number of hydroxyl groups which are substituted in the case of polyhydric alcohols is strictly limited. Like glyceiol, ethylene glycol gives a chlorhydrin, CIi..OH.CILOII 1- IICl CHnOH.CILCl -1- ILO. [Pg.260]

This is the basis of the iodofonn test for the CHiCO group. In addition to the.se reactions tliere is considerable industrial use for HOCl and hyfHxrhlorites in the manufacture of hydrazine (p. 427), chlorhydrins and or-glycols ... [Pg.860]

Fluoroalkanephosphonic acid can be obtained by addition of iodine perfluoroalkane to vinylphosphonic acid dichloride followed by saponification and deiodination by sodium amalgam [141]. Fluoroalkanephosphonic acids can be transformed to fluoroalkanephosphonic acid glycil esters by 2 mol of epi-chlorhydrin in a water-free solution followed by reaction with alkalines or amines [142]. Compounds of this kind with an alkyl chain of 8-20 carbon at-... [Pg.581]

The specific rate is k = 5.2 1 iter/gmol-hr at 82 C. Equal molal quantities the reactants are to be used. They are supplied as aqueous solutions, bicarbonate as 15 wt% and the chlorhydrin as 30 wt%. Production of glycol to be 20 kg/hr at 95% conversion. Specific gravity of the feed mixture 1.02. Find the required reactor volumes of a PFR and of a CSTR. [Pg.374]

Thus ethylene chlorhydrin is obtained by passing ethylene and carbon dioxide together into bleaching powder solution. [Pg.111]

On a large scale ethylene chlorhydrin is prepared by the addition of hypochlorous acid to ethylene, by passing C02 and ethylene simultaneously into a solution of bleaching powder. Concentrated potassium hydroxide solution converts chloroethyl alcohol into ethylene oxide, by removal of HC1 ... [Pg.116]

Special mention should be made of the ready conversion of the chlorhydrin, by means of tnmethylamine, to choline, a substance of great physiological importance. Choline chloride is obtained very easily when equimolecular amounts of the two components are made to interact for some time under the influence of heat a concentrated solution of the amine in absolute alcohol is used. [Pg.116]
