Abstract
1357008 Flocculating DIAMOND SHAMROCK CORP 26 April 1971 [27 April 1970] 11382/71 Heading C1C [Also in Divisions C2 and C3] Materials used as flocculants are watersoluble polyelectrolytes obtained by the reaction of a halogen-containing material bearing the halogens on the carbon chain and having a molecular weight of 500-5,000,000 and hydroxylamine, a primary, secondary or tertiary amine or a polyamine with at most one primary amine group in a mol. ratio of 2À5-45 mols. of amine for each halogen provided more than 10 moles per halo group are used in the case of hydroxylamine and primary, secondary and tertiary amines and optionally in the presence of 0-50 mols. of water. Exemplified halogen compounds are PVC, vinyl chloride-styrene copolymer, chlorinated polyethylene or polypropylene, or paraffin oil (C 20 -C 30 ), chlorodifluoroethylene-vinylidene fluoride copolymer and exemplified amines are N,N-dimethyl-1,3- propanediamine, n-butylamine, mono-, di- or tri-methylamine or ethylamine. The products are used as flocculants particularly in papermaking and for the treatment of sewage.
