US Patent:

42128102, Jul 15, 1980

Filed:

Dec 21, 1978

Appl. No.:

5/971940

Inventors:

Melvin H. Gitlitz - Edison NJ
John E. Engelhart - Westfield NJ
David A. Russo - Edison NJ

Assignee:

M&T Chemicals Inc. - Woodbridge NJ

International Classification:

A01N 928
C07D31750

US Classification:

2603405R

Abstract:

Many varieties of harmful insects which attack useful plant crops can be controlled by treating the plants with compositions containing certain novel tetraorganotin compounds wherein three of the four hydrocarbon groups bonded to the tin atom are methyl and the remaining group is phenyl containing specified substituents or heterocyclic and is either bonded directly to the tin atom or separated from the tin atom by one methylene group. The present compounds exhibit unexpectedly superior insecticidal activity relative to prior art organotin compounds containing three methyl groups and a phenyl or an alkyl- substituted phenyl group bonded to the tin atom.

Assignee:

Atochem North America, Inc. - Philadelphia PA

International Classification:

C09D 714

US Classification:

10628719

Abstract:

A liquid coating composition comprises an organotin di- or tricarboxylate and an organic fluoroacid for forming a fluorine-doped tin-oxide coating on glass having good bulk resistivity and haze values. The method of coating a transparent substrate with the composition is also described. The preferred liquid coating composition comprises about 50 to 80 wt. % of dibutyltin diacetate, and about 20 to 50 wt. % of trifluoroacetic acid.
