Description

В насто щее врем  хлораль в производстве ДДТ обг,1чно выдел етс  и; проД5КТОБ хлоригюилип  спирта с помощью jia:;iOHKii над серной кислотой.At present, chloral in the production of DDT obg is 1 time excreted and; Prod5KTOB hloriguilip alcohol with jia:; iOHKii over sulfuric acid.

При проведении операции разгонки до 5 %| хлорал   тер етс  за счет осмолени , вы,ыг(аемог() длительным кпнтактом его с li2S04 прп срат5нител1 но высокой температуре Д|) 11Й°.During the operation of distillation up to 5% | chloral is lost due to pitch, you, (aamog () by prolonged contact with li2S04 prp srat5nit11 but high temperature D |) 11 °.

Согласно изобретению, предлагаетс  нро ИЗВОДИТЬ выделение хлора л   из хлорированного масла с помощью отработанной серной кислоты со стадии конденсации х.торал  с хлорбензолом нри теинературе не свьпие 30° с последу1пп1,е1 экстракцией х.торал  хлорбензолом.According to the invention, it is proposed to extract NORO from chlorine from chlorinated oil using spent sulfuric acid from the stage of condensation of chlorine with chlorobenzene on non-30 ° with subsequent chlorobenzene.

При осуществлении данного способа выход хлорал  увеличиваетс  на 5 % и устран етс  расход куноросного масла за счет использовани  отхода стадии конденсации - отработанной cepHoii кислоты .With this method, the yield of chloral is increased by 5% and the consumption of crown-bonded oil is eliminated due to the use of a waste stage of condensation — spent cepHoii acid.

Затем добавл етс  70 мл хлорбензола и смесь перемешиваетс  в течение еще 30 мни. После этого дают смеси отсто тьс  в продолжение 1 часа и отдел ют хл(|рбензольный раствор хлорал  от кислотного сло .Then 70 ml of chlorobenzene is added and the mixture is stirred for another 30 minutes. Thereafter, the mixture is allowed to stand for 1 hour and chlorine is separated (chloral solution from the acid layer).

Последний экстрагируетс  2 раза 70 мл хлорбензола. Хлорбензольный раствор хлорал  вместе с 140 мл хлорбензола , примененного дл  экстракции, поступает на ))еакци1о конденсаоип, котора  П1)(П5()дитс  в присутствии 400 г укрепленной КИСЛОТ,.. содержащей 5.7% SO,.The latter is extracted 2 times with 70 ml of chlorobenzene. The chlorobenzene solution of chloral, together with 140 ml of chlorobenzene used for extraction, goes to)) condensation, which is P1) (P5 () is in the presence of 400 g of strengthened ACID containing 5.7% SO ,.
