Description
Technical field
The present invention relates to a kind of hygienic insecticide, and its preparation method and application.
Background technique
The pyrethroid compound that formula (1) indicates, 2,3,5,6- tetrafluoro-4-methoxymethyl benzyl base -3- (2,2- of chemical name
Difluoroethylene base) -2,2- dimethyl cyclopropane carboxylic acid's ester, there is insecticidal activity to be disclosed in the documents such as CN101306997；Separately
On the one hand, a kind of fan-type mosquito repellent utensil convenient to use is proposed in CN1159736A, wherein effective component uses tetrafluoro
It also proposed a kind of fan-type mosquito repellant convenient to use in benzene pyrethroids (Transfluthrin) and JP2004-222725A
Tool, wherein effective component uses dimefluthrin (Dimefluthrin) and metofluthrin (metofluthrin),
But we still feel the above pyrethroids its drug effect are not ideal enough as active constituent in actual use.Influence fan dosage form
The main factor of drug effect is activity and vapour pressure, only both has preferably performance to be just able to achieve fan dosage form application.
We have found that the pyrethroid compound that formula (1) indicates has very high vapour pressure, by vapour pressure after study
It arranges from high to low, formula (1) compound (2075.6Pa) > transfluthrin (1678.6Pa) > metofluthrin
(1323.8Pa) > dimefluthrin (1163.3Pa).Here vapour pressure is with Donovan method (by Stephen
