Description
Способы получени слабопол рных синтетических сорбентов путем поликонденсации ароматических кислот или оснований с формальдегидом в кислых водных растворах известны.Methods for preparing low polar synthetic sorbents by polycondensation of aromatic acids or bases with formaldehyde in acidic aqueous solutions are known.
Предлагаемый способ отличаетс от известных тем, что, с целью повышени сорбционной способности смол, реакцию провод т в присутствии параформа, добавл емого сверх необходимого количества формальдегида.The proposed method differs from the known ones in that, in order to increase the sorption capacity of the resins, the reaction is carried out in the presence of paraform added over the required amount of formaldehyde.
Пример реализации способа. В большой конденсационный бак помещают 428 л воды, 76,8 кг 30%-ной сол ной кислоты, 72 кг и1-фенилендиамина и 45,5 кг параформальдегида, а затем хорошо перемешивают смесь.An example implementation of the method. 428 l of water, 76.8 kg of 30% hydrochloric acid, 72 kg of I1-phenylenediamine and 45.5 kg of paraformaldehyde are placed in a large condensation tank, and the mixture is then well mixed.
В эту смесь быстро ввод т 151 кг 30%-ного водного раствора формальдегида . После быстро протекшей конденсации студень удал ют из бака и разламывают на куски. В течение 24 час смол ной студень обрабатывают вод ным паром при температуре не выше 100°С. После этого искусственна смола подвергаетс мокрому размолу и просеиваетс .151 kg of a 30% aqueous formaldehyde solution were quickly introduced into this mixture. After rapid condensation, the jelly is removed from the tank and broken into pieces. Within 24 hours, resinous jelly is treated with water vapor at a temperature not higher than 100 ° C. Thereafter, the artificial resin is wet ground and sieved.

Способность обесцвечивани , которой обладает искусственна смола по отношению к раствору патоки, измеренна по вышеприведенному способу, выражаетс цифрой 4500 единиц.The decolorization ability of the artificial resin in relation to the molasses solution, as measured by the above method, is expressed in 4500 units.
