Description

Предлагаетс  способ получени  смол нз сульфитцеллюлозных щелоксз или сульфитцеллюлозной барды, пригодных дл  производства текстолита, древесноволо книстых пл1ит и т. п. или в качестве кле  в производстве фанеры.A method is proposed for producing resins based on sulfite-cellulose alkali or sulfite-cellulose bards suitable for the production of textolite, wood-lined plitit, etc., or as an adhesive in the production of plywood.

Преимущество нредлагае.мого способа получени  смолы заключаетс  в экономии фенола и формалина.The advantage of the preferred method for producing resin is to save phenol and formalin.

По предлагаемому способу смолы получают слсдуюпдим образом.According to the proposed method, the resins are obtained according to the method.

Фенол и формалин, вз тые в соотношени х 1:3 (молей), конденсируют в присутствии едкого натра как катализатора при 65- -70 в теченлие 2,5 час., нейтрализуют реакционную оме.ь.до и, lie опдел.   воды от реакционной смеси, ввод т в нее 50%-ныи сульфитцеллюлозный щело-к или барду; после этого полученную водную суспензию смолы непосредственно или после нагревани  при 70-80 используют путем пропитывани  или промазывани  соответствуюни1Х материалоа 1- помощью известных приемов н последуюгцего нагревани  при 150-160.Phenol and formalin, taken in ratios 1: 3 (moles), are condensed in the presence of caustic soda as a catalyst at 65-70 for 2.5 hours, neutralize the reaction mixture, and lie down. water from the reaction mixture; 50% sulfite-cellulose lye-c or bardum is introduced into it; thereafter, the resulting aqueous suspension of the resin, either directly or after heating at 70-80, is used by impregnating or coating the corresponding materials with 1 using known methods and subsequent heating at 150-160.
