England article title : crotonic acid, 3-hydroxy-, methyl ester, dimethyl phosphate
(2-methoxycarbonyl-1-methyl-vinyl) - dimethyl-fosfaat
2-methoxycarbonyl-1 - methyl-vinyl) - dimethyl-phosphat
2-metossicarbonil-1-metil - vinil) - Ghitis - fosfato
traits Description : have the goods trans-isomer [298-01-1] and Z-isomers [338-45-4]. Cis-temperature 6.9 ° C and relative density of 1.245, 1.4524 refractive index. Trans-melting point of 21 ° C and relative density of 1.2345, 1.4452 refractive index. Speed eliminate phosphorus mixture of the two, trans content 60%. For pale yellow liquid boiling point 99-103 ° C (40Pa), the refractive index 1.4494. Vapor pressure (20 ° C) to 1.65 x 10-1100.
soluble in water, with alcohol, ketone solvent immiscible other slightly soluble ester hydrocarbon environment. Room temperature storage stable, soluble in hydrolysis. In alkaline hydrolysis in aqueous solution accelerated pH of 6:00 for the half-life of 120 days, the pH of the 9:00 half-life of 3 days, the pH of the 11:00 half-life of only 1.4h.
production methods : methyl acetate by using acetyl chloride, sulfur chlorination system of 2-chloro-methyl acetoacetate, and thereby trimethyl phosphite reaction in toluene rearrangement derived speed eliminate phosphorus (for commodities 40% EC).
purposes : eliminate speed is water-soluble phosphorus uptake tag and the organic phosphorus pesticides and acaricides. Insecticidal wide spectrum of cotton aphid, Kam boll worms, apple aphid, Apple spider mite, corn aphids, soybean aphid, Pieris rapae have better control effect.
