Description

Изобретение относитс  к способам выделени  жирных кислот с числом атомов углерод-а от 5 до 9 из водного раствора смеси жирных кислот с числом атомов углерода от 1 до 9, напри.мер. жирных кислот Cr,Hj,,O- - CuHjgO;, из вод1юго конденсата в ироизводстве синтетических жирных кислот, содержащего кислоты р да СН.,О., - СсН,,О,.The invention relates to methods for separating fatty acids with the number of carbon-a atoms from 5 to 9 from an aqueous solution of a mixture of fatty acids with the number of carbon atoms from 1 to 9, for example. fatty acids Cr, Hj ,, O- - CuHjgO ;, from water condensate in the production of synthetic fatty acids containing acids of the series CH., O., - ССН ,, О ,.

В сравнении с известным способом селективной экстракции предлагаемый способ значительно упрощает выделение указанных кислот из водного раствора.In comparison with the known method of selective extraction, the proposed method greatly simplifies the separation of these acids from an aqueous solution.

Особенность предлагаемого способа состоит в том, что нагретый до 50-бО водный раствор обрабатывают электролитом, обработанный раствор отстаивают и отдел ют всплывпшй слой жирных кислот.The peculiarity of the proposed method is that the aqueous solution heated to 50-bO is treated with electrolyte, the treated solution is settled and the floating layer of fatty acids is separated.

Способ осуществл етс  следуюп;им образом. Нагретый до температуры 50-60 водный раствор жирных кислот с кислотным числом около 300 при перемешивании обрабатывают электролитом , например, сухой глауберовой солью, вз той в количествеThe method is carried out as follows. Heated to a temperature of 50-60 an aqueous solution of fatty acids with an acid number of about 300 with stirring, is treated with an electrolyte, for example, dry Glauber's salt, taken in an amount

15-20% от водного раствора, или хлористым кальцием.15-20% of an aqueous solution, or calcium chloride.

После обработки указанными сол ми на поверхность водного раствора всп,1ывает часть жирных кислот, которые легко отдел ютс  от нижнего водного с,1о  простым декантированием после непродолжительного отсто , либо сепарированием .After treatment with these salts on the surface of the aqueous solution, a portion of the fatty acids, which are easily separated from the lower aqueous solution, is obtained with a simple decanting after a short sludge or separation.

Выделенный слой имеет кислотное число около 370, т, е. представл ет собой смесь кислот, содержащих атомы углерода в пределах чисел 5-9,The selected layer has an acid number of about 370, i.e. is a mixture of acids containing carbon atoms within the numbers 5-9,

Предлагаемый способ осуществл етс  в обычной аппаратуре стандартного типа, выполненной из кислотоупорных материалов.The proposed method is carried out in conventional standard type apparatus made of acid-resistant materials.

Предмет изобретени Subject invention

Способ выделени  жирных кислот с цеп ми, содержащими число атомов углерода от 5 до 9 из водного раствора смеси жирных кислот с чис,1ом атомов углерода от 1 до 9, например, жирных кислот Cj.HjoOo -Cc.iHigO из водного конденсата в производстве синтетических жирных кислот, содержащего смесь жирнь1Х кислот СЬьО. - СзН18О2, отличающийс  тем, что, с целью ускорени  процесса и устранени  операции селективной экстракции, на .водный раствор смеси, нагретый до 50--60, воздействччот электролитом, например , глауберовой солью или хлористым кальцием, а всплывающий слой кислот с числом атомое углерода от 5 до 9 отдел ют после отстаивани .A method for separating fatty acids with chains containing from 5 to 9 carbon atoms from an aqueous solution of a mixture of fatty acids with 1 to 9 carbon atoms, for example, Cj.HjoOo-Cc.iHigO fatty acids from aqueous condensate in the production of synthetic fatty acids containing a mixture of fatty acids СЬО. - SzN18O2, characterized in that, in order to accelerate the process and eliminate the operation of selective extraction, an aqueous solution of the mixture heated to 50--60 is affected by an electrolyte, for example, Glauber's salt or calcium chloride, and the emerging layer of acids with carbon atom 5 to 9 are separated after settling.
