Изобретение относитс к получению не описанных в литературе кремнийорганических производных ТИОКИСЛОТ трехвалентного мышь ка , которые обладают фунгицидной активностью и примен ютс дл изготовлени покрытий , защищающих оптические детали от микробиологического обрастани .The invention relates to the production of organosilicon derivatives of trivalent arsenic acid Tioxyacid, which are not described in literature, which possess fungicidal activity and are used to make coatings that protect optical components from microbiological fouling.
Предлагаемый способ основан на реакции переэтерификации и заключаетс во взаимодействии алкиловых эфиров кислот трехвалентного мыщь ка с триалкоксисилилалкилмеркаптанами при нагревании, например до кипени , с последующим выделением целевого продукта известными методами. Реакци идет по схеме:The proposed method is based on the transesterification reaction and consists in the interaction of alkyl esters of trivalent mice with trialkoxysilylalkyl mercaptans when heated, for example until boiling, followed by isolation of the target product by known methods. The reaction goes according to the following scheme:
RJ, А8(ОЛ1К;з-п (3-п)НЗ()гпй1(ОК )з 5(CH.7)mSi(OR) (3-n)ALkOHRJ, A8 (OL1K; sn (3-p) NS) () gpy1 (OK) s 5 (CH.7) mSi (OR) (3-n) ALkOH
где R - алкил, арил, гетероцикл;where R is alkyl, aryl, heterocycle;
R - СНз или CsHs; Alk-СНзИли С2Н5; п -О, 1, 2; m -2, 3.R is CH3 or CsHs; Alk-CH3 or C2H5; n, 1, 2; m -2, 3.
Полученные тиоэфиры представл ют собой бесцветные или слабо окращенные в желтый цвет густые жидкости, обладающие слабым специфическим запахом. Они хорошо раствор ютс в органических растворител х, гидролизуютс водой с разрывом св зи кремний - кислород. Выход продуктов практически количественный . Продукты реакции не требуют очистки.The resulting thioethers are colorless or slightly yellow-colored thick liquids with a low specific odor. They dissolve well in organic solvents, hydrolyze with water to break the bond between silicon and oxygen. The yield of products is almost quantitative. The reaction products do not require purification.
Пример. Получение ди-р- (триэтоксисилил )-этилового эфира этилдитиоарсонистой кислоты.Example. Preparation of di-p- (triethoxysilyl) ethyl ethyl dithioaronic acid ester.
К 4,0 г диэтилового эфира этиларсонистой кислоты прибавл ют при перемещивании 9,25 г р-(триэтоксисилил)-этилмеркаптана, наблюда небольшой разогрев смеси. Смесь нагревают до кипени , отгон ют образовавшийс этанол, нагревают остаток на вод ной бане в вакууме дл полного удалени этанола и затем анализируют. Выход 11,3 г (99,9%).9.25 g of p- (triethoxysilyl) -ethyl mercaptan was added to 4.0 g of ethyl ethyl acetate diethyl, while slight mixing of the mixture was observed. The mixture is heated to boiling, the ethanol formed is distilled off, the residue is heated on a water bath under vacuum to completely remove the ethanol and then analyzed. The yield of 11.3 g (99.9%).

Предмет изобретени Способ получени триалкоксисилилалкиловых эфиров тиокислот трехвалентного мышь ка , отличающийс тем, что триалкоксисилил- 5 Густой мазеобразный продукт гр зно-зеленого цвета, не кристаллизующийс при хранении. алкилмеркаптан обрабатывают алкиловым эфиром кислоты трехвалентного мышь ка при нагревании, например до кипени , с последуюш ,им выделением целевого продукта известными приемами.Calculated,%: As 13.60; S 11.64. Compounds listed in the table are synthesized in a similar way. The subject of the invention is a method for the preparation of trialkoxy-silylalkyl esters of trivalent arsenic thioacids, characterized in that trialkoxy-silyl-5 Dense greasy-green greasy-green product that does not crystallize during storage. The alkyl mercaptan is treated with the alkyl ester of the trivalent arsenic when heated, for example until boiling, followed by extracting the target product by known methods.
