55 г (0,3 моль) 2-этилсульфоксилметилфенола (густотекучее масло оранжевого цвета, п д 1,5665) раствор ют в 500 мл эфира и добавл ют 5 мл 95%-ного триэтиламина . Затем, охлажда , прикапывают при 20°С 20,5 г (0,36 моль) метилизоцианата. После 2 ч последовательного перемешивани отсасывают кристаллизат и получают 40 г (55,5% теории) эфира Ы-метил-0-(2этилсульфоксилметилфенил )- карбаминовой кислоты. Серо-белые, зернистые с ограниченной растворимостью в воде, кристаллы можно нерекристаллизовывать из смеси уксусный эфир-простой эфир (2 : 1, 1 г/10 мл) и получать кристаллы с т. пл. 75°С.55 g (0.3 mol) of 2-ethylsulfoxylmethylphenol (thick orange-colored oil, p 1.5665) is dissolved in 500 ml of ether and 5 ml of 95% triethylamine are added. Then, cooling, at 20 ° C, 20.5 g (0.36 mol) of methyl isocyanate. After successive stirring for 2 hours, the crystallized crystals are sucked off to obtain 40 g (55.5% of theory) of N-methyl-0- (2-ethylsulfoxymethyl-phenyl) -carbamic acid ester. Gray-white, granular with limited solubility in water, the crystals can be non-recrystallized from a mixture of acetic ether-ether (2: 1, 1 g / 10 ml) and get crystals with so pl. 75 ° C.

60 г (0,3 моль) 2 - этилсульфонилметилфенола (т. пл. 92°С из бензола) суспендируют или слегка раствор ют в 500 мл эфира . После добавлени 5 мл триэтиламина прикапывают при 20°С 20,5 г (0,36 моль) метилизоцианата. Экзотермической реакции при этом не наблюдаетс . После 2 ч последовательного перемешивани отсасывают кристаллизат.и дополнительно промывают эфиром. Из уксусного эфира (1 г/10 мл) получают 69 г (89,5% теории) эфира N-метил - О - (2 - этилсульфонилметилфенил )-карбаминовой кислоты в виде бесцветных иголок с т. пл. 123°С.60 g (0.3 mol) of 2-ethylsulfonylmethylphenol (mp. 92 ° C from benzene) are suspended or slightly dissolved in 500 ml of ether. After adding 5 ml of triethylamine, 20.5 g (0.36 mol) of methyl isocyanate are added dropwise at 20 ° C. No exothermic reaction is observed. After 2 hours of stirring successively, crystallized precipitates are suction filtered and washed with ether. 69 g (89.5% of theory) of N-methyl-O- (2-ethylsulfonylmethylphenyl) -carbamic acid ester in the form of colorless needles with m. Pl. Are obtained from acetic ester (1 g / 10 ml). 123 ° C.
Аналогично примеру 1 или 2 можно из 2 - метилсульфоксилметилфенола (т. пл. 123°С) или из 2 - метилсульфонилметилфенола (т. пл. 118°С) получают другие карбаматы .Analogously to example 1 or 2, it is possible from 2 - methylsulfoxylmethylphenol (mp. 123 ° C) or from 2 - methylsulfonylmethylphenol (mp. 118 ° C) to obtain other carbamates.
Строение и свойства карбаматов приведены в табл. 1.The structure and properties of carbamates are given in table. one.
Формы применени средства обычные: растворы, эмульсии, суспензии, порошки, пасты, гранул ты. Их приготавливают общими методами изготовлени препаративных форм пестицидов.Forms of application are usual: solutions, emulsions, suspensions, powders, pastes, granules. They are prepared by general methods for the manufacture of pesticide formulations.
