Description

Изобретение относитс  к области получени  веществ, обладающих инсектицидными свойствами.The invention relates to the field of obtaining substances with insecticidal properties.

Получаемое по описываемому способу вещество р-родан- -хлордиэтиловый эфир обладает сильным инсектицидным действием, уничтожа  насекомых и обеспложива  их  йца.Obtained by the described method, the substance p-rodane-chloro-ethyl ether has a strong insecticidal effect, destroying insects and securing their eggs.

Отличие описываемого способа получени  р-родан-р-хлордиэтилового эфира и применени  его заключаетс  Б том, что 3, р-дихлордиэтиловый эфир нагревают в среде метанола или этанола с роданистой солью, вз той в эквимолекул рном количестве, а образовавшийс  р-рода н-р-хлордиэтиловый эфир выдел ют далее известными методами и используют в виде дустов, растворов или эмульсий дл  борьбы с насекомыми.The difference between the described method of obtaining p-rhodan-p-chlorodiethyl ether and its application consists in the fact that 3, p-dichlorodiethyl ether is heated in methanol or ethanol with a rhodium salt, taken in equimolecular amount, and the resulting p-type n- p-Chloro diethyl ether is isolated further by known methods and is used in the form of dusts, solutions or emulsions for the control of insects.

По описываемому способу, -родан- -хлордиэтиловый эфир получают и примен ют следующим образом.In the process described, -rod-chloro-diethyl ether is prepared and used as follows.

В стекл нную трубку внос т 20 гр, S-дихлордиэтилового эфира, 27 г роданистого кали  в 90 мм метилового спирта. Трубку запаивают и нагревают на кип щей вод ной бане в течение .15 часов,20 g, S-dichlorodiethyl ether, 27 g of rhodium potassium in 90 mm of methyl alcohol are introduced into the glass tube. The tube is sealed and heated in a boiling water bath for .15 hours,

Затем, после охлаждени , трубку вскрывают, спирт отгон ют, а остаток разбавл ют водой.Then, after cooling, the tube is opened, the alcohol is distilled off, and the residue is diluted with water.

Продукт реакции можно проэкстрагировать серным эфиром или с небольшими потер ми отделить от водного сло . Эф|ирную выт жку промывают водой до отсутстви  реакции на галоид, сущат над хлористым кальцием, затем эфир отгон ют , остаток фракцинируют. Получают 11 г сырого 8-родан-р-хлордиэтилового эфира. Очищенный 3-родан-8-хлордиэтиловый эфир представл ют собой прозрачную, светлую жидкость dlo - 1,230 г,The reaction product can be extracted with sulfuric ether or separated from the aqueous layer with small losses. The effluent is washed with water until no reaction to the halogen exists, it is dissolved over calcium chloride, then the ether is distilled off, the residue is fractionated. 11 g of crude 8-rhodane-p-chlorodiethyl ether are obtained. The purified 3-rhodane-8-chlorodiethyl ether is a clear, clear liquid dlo - 1.230 g,

гд-1,5080.gd-1.5080.

Полученный S-родан-р-хлордиэтиловый эфир может быть применен в форме 0,1%-ного водного раствора или 1%-ного талькового дуста дл  100%-ного уничтожении, например, хризантемной т.щ, или в виде водного раствора е 0,3% хоз йственного мыла дл  100%-ного уничтожени , например  иц  блонной мед ницы.The resulting S-rhodan-p-chloro-diethyl ether can be used in the form of a 0.1% aqueous solution or 1% talc dust for 100% elimination, for example, chrysanthemum, etc., or as an aqueous solution of e 0 , 3% of household soap for 100% destruction, for example, blonid's honey.
