Description

п -- средн   в&тичина 7.n - average 7.

№143796- 2 -:No. 143796-2 -:

Из раствора в скипидаре смола образует совершенно бесцветные пленки.., ,i. :From the solution in turpentine, the resin forms completely colorless films ..,, i. :

Описываема  смола, |в отличие от смолы, получаемой по авт. св. ЛЬ 80924, обладает значительно большим молекул рным весом, полным отсутствием, гидцоксил;ьных групп и чистотой белого цвета.The described resin, | in contrast to the resin obtained by ed. St. LL 80924, has a significantly greater molecular weight, complete absence, hydroxyl, ny groups and purity of white.

Примёр. Смец1йваю,т.10 г циклогексанона с 20 мл 0,5 н. спиртового раствора едкого натра, нагревают до 70-75° и при энергичном перемешивании в течение 30 глин ввод т 9 1лл 34%-него раствора формалина. После охлаждени  смесь нейтрализуют слабой сол ной кислотой до слабокислой реакции на конго. Высадившийс  при этом осадок смолы отдел ют декантацией, промывают водой до прекращени  реакции на хлор и высушивают в вакууме. Получают 9,5 г продукта с темп, плавлени  116-159° (1-а  фракци ).Example. Smelt, 10 grams of cyclohexanone with 20 ml 0.5 n. an alcoholic solution of sodium hydroxide, heated to 70-75 °, and with vigorous stirring, 9 1ll of a 34% formalin solution is injected over 30 clays. After cooling, the mixture is neutralized with weak hydrochloric acid to slightly acidic reaction to congo. The precipitated resin thus separated is decanted, washed with water until the reaction to chlorine is terminated and dried in vacuo. 9.5 g of product are obtained with a melting rate of 116-159 ° (1-a fraction).

Из маточного раствора, после удалени  спирта и разбавлени  водой , высаживают вторую фракцию смолы в количестве 1,6 г с темп, плавлени  53-100°.From the mother liquor, after removing the alcohol and diluting with water, a second fraction of the resin is precipitated in an amount of 1.6 g with a temp, melting 53-100 °.

Приведенные результаты анализов и расчеты подтверждают, что полученные по описанному способу вешества  вл ютс  поли1сетонами общего строени  I.The results of the analyzes and calculations confirm that the materials obtained by the described method of the substance are polysetons of general structure I.

Предмет изобретени .The subject matter of the invention.

Способ получени  циклогексанонформальдегидной смолы путем конденсации циклогексанона с формальдешдом в присутствии спир-. товой шелочи, отличающийс  тем, что, с целью расширени  ассортимента пленкообразующих материалов, в смесь диклогексанона и спиртовой щелочи ввод т эквимолекул рное количество формальдегида при 70-75°.The method of producing cyclohexanone formaldehyde resin by condensation of cyclohexanone with formaldehyde in the presence of alcohol. It is characterized by the fact that, in order to expand the range of film-forming materials, an equimolecular amount of formaldehyde at 70-75 ° is introduced into the mixture of diclohexanone and alcohol alkali.
