Дл различных технических назначений требуютс смолы, которые твердеют при нагревании.или на холоду и дают неплавкие и нерастворимые продукты. Такие смолы примен ютс , дл склейки различных материалов, заливки пор, получени формованных изделий без больших давлений и т. д.Resins that harden when heated or cold and produce infusible and insoluble products are required for various technical uses. Such resins are used to glue various materials, to fill in pores, to obtain molded products without high pressures, etc.
Автор установил, что смолы такого типа можно получить посредством конденсации с альдегидами ароматических аминов и ароматических сульфокислот, полученных сульфированием различных углеводородов с конденсированными драми.The author found that resins of this type can be obtained by condensation with aldehydes of aromatic amines and aromatic sulfonic acids obtained by the sulfonation of various hydrocarbons with condensed cores.
П р и м е р 2. 2 в. ч. |3-нафталинсульфокислоты, 1 щ. ч. анилина и 2 в. ч. 40%-ного формалина конденсируют в присутствии спирта, количество которого составл ет 20-50% от веса всех вз тых компонентов . В смеси спирта с анилином раствор ют нафталинсульфокислоту, затем при температуре не выше 30-40° ввод т формалин; спуст некоторое врем начинаетс экзотермическа реакци конденсации. В зависимости от температурных условий можно получить смолу, котора при обыкновенной температуре переходит в неплавкое и нерастворимое состо ние . Смола .имеет красный цвет, водостойка и отличаетс малой горючестью. Она может найти применение дл склеивани и пропитки материалов в тех же област х, где используютс фенолоформальдегидные смолы. Возможно также применение таких смол дл получени прессовочных композиций.PRI mme R 2. 2. h | 3-naphthalenesulfonic acid, 1 y. including aniline and 2 in. 40% formalin is condensed in the presence of alcohol, the amount of which is 20-50% by weight of all components taken. Naphthalene sulfonic acid is dissolved in a mixture of alcohol and aniline, then formalin is introduced at a temperature not higher than 30-40 °; after some time, the exothermic condensation reaction begins. Depending on the temperature conditions, a resin can be obtained, which at ordinary temperatures goes into a non-melting and insoluble state. The resin has a red color, is water resistant and has a low flammability. It can be used for bonding and impregnating materials in the same areas where phenol formaldehyde resins are used. It is also possible to use such resins for the preparation of molding compositions.
Конденсацию можно осуществить также по сухому методу, дл чего сульфокислоту сплавл ют с амином и твердыми полимерами формальдегида или гексаметилентетрамином. Гораздо труднее проходит конденсаци в водной среде, так как сульфокислота трудно растворима в воде.The condensation can also be carried out using a dry method, for which the sulfonic acid is fused with an amine and solid polymers of formaldehyde or hexamethylenetetramine. Condensation in an aqueous medium is much more difficult, since sulfonic acid is difficult to dissolve in water.
В случае замены формальдегида другими альдегидами, как, например , уксусным альдегидом, масл ным альдегидом, фурфуролом, реакци проходит хорошо, так как сульфокислоты раствор ютс в указанных безводных альдегидах.In case of replacing formaldehyde with other aldehydes, such as, for example, acetic aldehyde, oil aldehyde, furfural, the reaction proceeds well, since sulfonic acids dissolve in said anhydrous aldehydes.
Использование сульфокислот нафталина, антрацена, фенантрена и карбазола совместно с ароматическими аминами может значительноThe use of naphthalene, anthracene, phenanthrene and carbazole sulfonic acids together with aromatic amines can significantly
