Fentin acetate is a chemical compound from the group of organotin compounds and the acetic acid esters of fentin .
Extraction and presentation
Fentin acetate can be obtained by reacting chlorobenzene with magnesium , tin tetrachloride in a Grignard reaction and subsequent reaction with acetic acid.
properties
Fentin acetate is a flammable colorless solid with an aromatic, slightly acidic odor that is practically insoluble in water. It decomposes when heated. Fentin acetate is stable when dry, but hydrolyzes rapidly in the presence of water.
use
Fentin acetate is used as a fungicide . It can also be used as a herbicide against algae in rice fields and as a molluscicide. It was developed by Van der Kerk and Luijten in the 1950s.
Admission
Fentin acetate was approved in the FRG between 1971 and 1997, in the GDR until 1994.
The EU Commission decided in 2002 not to include fentin acetate in the list of permitted active ingredients in pesticides according to Annex 1 of Directive 91/414 / EEC.
In Germany, Austria and Switzerland, no pesticides with this active ingredient are permitted.
