Propargite is a chemical compound from the group of Organosulfite ( esters of sulfurous acid).

Production and representation

Propargite can be prepared by reaction of 4-tert- butylphenol with 1,2- epoxycyclohexane, followed reaction with thionyl chloride, and propargyl alcohol in the presence of a base.

Properties

Is propargite as a technical product is a yellowish brown liquid which is practically insoluble in water.

Use

Propargite is outside Europe as plant protection products ( acaricide ) under the brand name Omite and Comite. The drug was approved in 2011 are not the European Union. In the EU countries Bulgaria, Cyprus, Portugal, Poland and Slovakia pesticides can still be used with propargite, the use- ends no later than the end of 2012. Was first registered in 1969 in the United States.
