Description

Предлагаемое изобретение относитс  к - способам получени  обезвоженного спиртового раствора или твердой резольной фенолоальдегидной смолы, перешедшей частично или полностью в стадию В, с применением органических растворителей .The present invention relates to methods for the preparation of a dehydrated alcohol solution or a solid rezol phenolic resin, converted partially or completely to stage B, using organic solvents.

5 описываемом способе смолу раствор ют в спиртовом растворе щелочи и после растворени  прибавл ют бензин, бензол или другие легко кип щие углеводороды . При после |/ющей отгонке получаетс  сначала смолы в абсолютном спирте, и удалением спирта под вакуумом получаетс  обезвоженна  тверда  смола. Отогнанные бензин, бензол или другие углеводороды могут вновь служить дл  обезвоживани  новых порций резольных смол.5 of the described method, the resin is dissolved in an alcoholic alkali solution and, after dissolving, gasoline, benzene or other easily boiling hydrocarbons are added. Upon post-distillation, the resins are first obtained in absolute alcohol, and the anhydrous solid resin is obtained by removing the alcohol under vacuum. The distilled gasoline, benzene, or other hydrocarbons can again serve to dehydrate new portions of resole resins.

Пример: 100 частей резольной в стадии В обрабатывают до растворени  100 част ми спиртового раствора едкого натра (10%). К раствору добавл етс  смесь из 100 частей бензола и 50 частей бензина, и полученна  смесь подвергаетс  отгонке под вакуумом дО прекращени  перехода мутной жидкости. Полученный лак может непосредственно примен тьс  в промышленности.Example: 100 parts of resolum in stage B are treated to dissolve 100 parts of caustic soda solution in alcohol (10%). A mixture of 100 parts of benzene and 50 parts of gasoline is added to the solution, and the resulting mixture is stripped under vacuum until the turbid liquid transition is stopped. The resulting lacquer can be directly applied in industry.

Предмет изобретени .The subject matter of the invention.

Способ получени  обезвоженного спиртового раствора или твердой резольной фенолоальдегидной смолы, перешедшей частично или полностью в стадию В, с применением органических растворителей , отличающийс  тем, что смолу раствор ют в спиртовом растворе щелочи, прибавл ют бензин, бензол или другие легко кип щие углеводороды и подвергают отгонке до удалени  воды и углеводорода или до получени  твердой смолы.The method of obtaining a dehydrated alcoholic solution or solid rezol phenolic resin, partially or completely transferred to stage B using organic solvents, characterized in that the resin is dissolved in an alcoholic alkali solution, benzine, benzene or other boiling hydrocarbons are added and subjected to distillation until water and hydrocarbon are removed or solid resin is obtained.
