Abstract
Abstract Microbiocidally active compounds comprising the condensation products of 1,4-dihalo-2-butene and difunctional tertiary amines of the type: <IMAGE> wherein Z is a cyclic or acyclic divalent aliphatic radical of 2 to 10 carbon atoms which may contain 0 to 2 double bonds or 0 to 2 hydroxy substituents; and wherein R' and R'' are either the same or different and where they may be either (a) primary or secondary alkyls having 1 to 20 carbon atoms with a total sum of no greater than 36 carbon atoms, (b) hydroxy or dihydroxy derivatives of the aforesaid primary or secondary alkyls, (c) benzyl, (d) alkyl-benzyl, or (e) combined with N to form a heterocyclic group.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
115 words
A method of controlling the proliferation of bacteria which comprises applying to said bacteria an effective amount to inhibit said bacteria of a product formed by the condensation of 1,4-di-halo-2-butene and a difunctional tertiary amine, said difunctional tertiary amine being selected from the group consisting of di-lower-alkyl piperazine, 1,4-diazabicyclo (2.2.2) octane, and an amine of the formula: ##STR7## wherein Z is a divalent aliphatic radical of 2 to 10 carbon atoms containing from 0 to 2 double bonds and from 0 to 2 hydroxy substituents and wherein R' and R" are part of a heterocyclic group when combined with N, said heterocyclic group being selected from the group consisting of N-piperidino, N-pyrrolidino, N-morpholino and N-homopiperidino.
Claim 2
Independent Claim
115 words
A method of controlling the proliferation of bacteria which comprises applying to said bacteria an effective amount to inhibit said bacteria of a product formed by the condensation of 1,4-di-halo-2-butene and a difunctional tertiary amine, said difunctional tertiary amine being selected from the group consisting of di-lower-alkyl piperazine, 1,4-diazabicyclo (2.2.2) octane, and an amine of the formula: ##STR7## wherein Z is a divalent aliphatic radical of 2 to 10 carbon atoms containing from 0 to 2 double bonds and from 0 to 2 hydroxy substituents and wherein R' and R" are part of a heterocyclic group when combined with N, said heterocyclic group being selected from the group consisting of N-piperidino, N-pyrrolidino, N-morpholino and N-homopiperidino.
Claim 3
