Description

Известен способ получени  алкилмеркаптоацетальдегидов. Однако получен только один представитель этого р да, а именно - этилмеркаптоацетальдегид .A known method for producing alkyl mercapto acetaldehydes. However, only one representative of this series was obtained, namely ethyl mercapto acetaldehyde.

Предлагаемый способ отличаетс  тем, что а-хлор-р-алкилмеркаптоэтиловые эфиры алифатических одноосновных кислот подвергают гидролизу. Это позвол ет расширить сырьевую базу и ассортимент серосодержащих альдегидов.The proposed method is characterized in that the a-chloro-p-alkyl mercaptoethyl esters of aliphatic monobasic acids are hydrolyzed. This allows the raw material base and the range of sulfur aldehydes to be expanded.

При осуществлении способа а-хлор-р-этилмеркаптоэтиловый эфир кип т т с водой. Продукт экстрагируют эфиром.In the process, the a-chloro-p-ethyl mercapto ethyl ether is boiled with water. The product is extracted with ether.

Пример. 73 г (0,4 мол ) а-хлор-р-этилмеркаптоэтилового эфира уксусной кислоты смешивают с 500 Л1Л воды и смесь при перемещивании кип т т 2 час. После охлаждени  смесь экстрагируют эфиром, выт жку сущат сульфатом натри  и перегонкой.Example. 73 g (0.4 mol) of a-chloro-p-ethylmercaptoethyl acetate are mixed with 500 L1L of water and the mixture is boiled for 2 hours while being stirred. After cooling, the mixture is extracted with ether, and the residue is extracted with sodium sulfate and distilled.

Выход этилмеркаптоацетальдегида после двух перегонок 17,5 г (42%).The yield of ethyl mercapto acetaldehyde after two distillations is 17.5 g (42%).

Свойства: температура кипени  47° (18 мм), - 1,0400, Пл2° - 1,4766, MR - 28,24 (найдено), MR - 28,75 (вычислено.).Properties: boiling point 47 ° (18 mm), - 1.0400, PL2 ° - 1.4766, MR - 28.24 (found), MR - 28.75 (calculated.).

Состав, %: С-46,26 и 46,53. Н-7,39 и 7,52; S - 29,60 и 29,32 (найдено) и вычислено дл  С4Н8О С-46,2, Н-7,7; S-30,75.Composition,%: C-46.26 and 46.53. H-7.39 and 7.52; S — 29.60 and 29.32 (found) and calculated for C4H8O C-46.2, H-7.7; S-30.75.

Этилмеркаптоацетальдегид растворим в обычных органических растворител х.Ethyl mercapto acetaldehyde is soluble in common organic solvents.

Аналогично получен метилмеркаптоацетальдегид с 32%-ным выходом .Similarly, methyl mercapto acetaldehyde was obtained in 32% yield.

Свойства: температура кипени  - 45° (30 мм), - 1,0663, - 1,4814, MR (вычислено) -24,13, MR (найдено) -24,03.Properties: boiling point - 45 ° (30 mm), - 1.0663, - 1.4814, MR (calculated) -24.13, MR (found) -24.03.
