LONG ACTING INDUSTRIAL BACTERICIDAL AND BACTERIOSTATIC AGENT AND LONG ACTING BACTERICIDAL AND BACTERIOSTATIC METHOD FOR INDUSTRY

摘要

PROBLEM TO BE SOLVED: To obtain the subject bactericidal agent capable of affording a lasting slime-depression effect and especially, continuously preventing rotting of a lignin waste solution and useful for preserving and bactericidal purposes of water, etc., used in a paper making process of paper and pulp industries. ;SOLUTION: This long acting industrial bactericidal and bacteriostatic agent is obtained by mixing methylene bis(thiocyanate) with a halogenated acetic acid ester derivative (e.g. 1,2-bisbromoacetoxyethane) expressed by formula I (X is a halogen; Y is a lower alkylene or alkenylene) and adding a little amount of a isothiazolone derivative (e.g. 5-chloro-2-methyl-4-isothiazoline-3-one). It is preferable to mix 0.1-10 pts.wt. of the component I with 1 pt.wt. of methylene bis(isothianate), while 0.01-0.2 pt.wt. of the isothiazolene derivative with 1 pt.wt. of the sum weight of methylene bis(isothianate) and the component of formula I.;COPYRIGHT: (C)1997,JPO
