Description

В ОСНОВНОМ патёнте Jfc 2035 описано .получение продуктов конденсации фенолов Q альдегидами, окрашенных в прочный, черный цвет, при чем окраска происходит sa счет черной смолы, котора  получаетс  при взаимодействни фенолов с фурфуролом в присутствии минеральных кислот. Так как избыток минеральных кислот вреден дл  получени  не1йавких и нерастворимых п.1астнческих продуктов конденсапии, то его: представл лось  еобхрдимым отмывать водой, а воду удал ть при помощи упаривани . . - Дальнейшими опытами автор нащел, что хорошую фурфурольную СМОЛ7 (способ , ную служить красителем в черный двет) можно получнть, если, взаимодейс,тв2е фенОла , или крезолов осуп1;ествл ть в. присутствии сульфоновых кислот, по.дучаемых сульфированием высококип п их углеводо , родов полиметиленового р да, гидрированных ароматических углеводородов или л сульфоароматических жирных кислот. Пример: Смешивают 100 ч. жидкой карболовой кислоты,. 40 ч. фурфурола, 10 ч. ,сульфоновь1х кислот нефт ных ушеводорочДов , известных под названием «контакт. Смесь нагреваетс  с обратным холодильником при температуре 80-90° С до . Тип. Гидрогр. Упр. Управл. В.-М. Сил РКК образовапн  начального продукта конденсации . Образовавша с  смола без предварительного промывани  водой, увариваетс  до желаемой консистенции, при чем она обезвоживаетс . Полученна  вышеуказанным образом кисла  смола, содержаща  сульфокиедоты, служит одновременно и- как краситель при получен1а й продуктов конденсации фенола или крезолов с другими альдегидами, напр., уксусным формальдегидом, акролеином и т. д., и как катализатор при превращвнии начальных продуктов конденсации (резолей) в неплавкие и нерастворимые продукты, резиты. t Предмет патент а. Прием выполнени  способа окрашивани  ,B чёрный цвет продуктов коиденсаци фенолов с формальдегидом, означенного в предмете патента № 2035, а также дл  превраш,ени  образу юш,ихс  при начальном процессе, конденсайди резолей в резиты, отличающийс  тем, что к реакционной массе во врем  конденсации прибавл ют продукт конденсации фенолов с фурфуролом при содействии сульфонОвых кислот, вз тых в качестве катализатора. . Ленинград, здание Г.ч. АдмиралтействаThe main Jfc 2035 patent describes the preparation of condensation products of phenols Q with aldehydes painted in a strong, black color, the color being due to black resin, which is obtained by the interaction of phenols with furfural in the presence of mineral acids. Since the excess of mineral acids is harmful for the preparation of unsound and insoluble 1 st seeds of condensation, it was: it was necessary to wash it with water, and to remove water by evaporation. . “By further experimentation, the author said that good furfurol SMOL7 (a way to serve as a black dye dye) can be obtained if interaction, solid phenol, or cresol is impaired; the presence of sulfonic acids obtained by the sulfonation of high-boiling hydrocarbons, polymethylene species, hydrogenated aromatic hydrocarbons or l sulfonic aromatic fatty acids. Example: Mix 100 parts of liquid carbolic acid ,. 40 hours of furfural, 10 hours, sulfonic acids of petroleum acids, known as “contact. The mixture is heated under reflux at a temperature of 80-90 ° C to. Type of. Hydro Exercise Manage V.-M. Forces RKK obrazapn initial condensation product. Formed from the resin without prior washing with water, boil down to the desired consistency and dehydrate. The sulfoxydote-containing acidic resin obtained in the above manner simultaneously serves as a dye for the condensation products of phenol or cresols obtained with other aldehydes, for example, acetic formaldehyde, acrolein, etc., and as a catalyst in the transformation of the initial condensation products (resole a) into infusible and insoluble products, are cut. t Subject patent a. Acceptance of the dyeing process, B, the black color of the products of the co-condensation of phenols with formaldehyde, mentioned in the subject of patent No. 2035, as well as to transform them during the initial process, the condensides of the resols into resites, characterized in that the reaction mass during condensation the condensation product of phenols with furfural is added with the assistance of sulfonic acids taken as a catalyst. .
