METHOD OF SYNTHESIS OF REAGENT FOR SULFATE-REDUCING BACTERIA GROWTH INHIBITION Russian patent published in 1994 - IPC

FIELD: organic chemistry. SUBSTANCE: synthesis is carried out by reaction of hexamethylenetetramine with unsaturated chlorohydrocarbon, which is a waste in glycerol production - light fraction of chlorohydrocarbon. The latter has the following composition, wt. -% : 2,3-epoxy-1-chloropropane 0.01-11.1; 3-chloropropene-1 3.98-48.02; 1,3- and 2,3-dichloropropenes 9,87-38.86, and saturated chlorohydrocarbon containing chloroform up to 100. Reaction is carried out at 55-60 C. Under these conditions filtration and drying of the end product are excluded, reaction time is decreased by two-fold, valuable by-side product, chloroform, is isolated. Activity of the end product exceeds that obtained from urotropin and allyl chloride. EFFECT: enhanced activity of product, intensified process. 1 tbl
