Description
По описываемому способу искусственные смолы получают путем конденсации меламина, аммелипа, аммелида и бензогуанамида с аллиловым спиртом.According to the described method, artificial resins are obtained by condensation of melamine, ammelip, ammelide, and benzoguanamide with allyl alcohol.
В производственных услови х конденсаци может ОЫТЕ, осуществлена следующим образом.Under production conditions, condensation can be carried out as follows.
Пример 1. 1,63 вес. ч. меламина подогревают с 240 вес. ч. 37%-нО|ГО раствора формалина при рП 7,5 и температуре 60-70° до полного растворени мелампна. Смесь упаривают в вакууме до содержани 70-75% твердого вещества, после чего к ней добавл ют по 200 вес. ч. аллилового спирта и бензола, а также кислоту в количестве , необходи.мом дл нейтрализаццц массы.Example 1. 1,63 weight. h. Melamine is heated with 240 weight. 37% -NO | GO solution of formalin at pH of 7.5 and a temperature of 60-70 ° until mellapne is completely dissolved. The mixture is evaporated in vacuum to a content of 70-75% solids, after which 200 weight by weight is added to it. including allyl alcohol and benzene, as well as an acid in an amount necessary to neutralize the mass.
Полученную смесь концентрируют в вакууме до содержани 60-65% твердых составных веществ.The resulting mixture is concentrated in vacuo to a content of 60-65% solids.
Пример 2. 155 вес. ч. мономети.толмеламина. 72 вес. ч. аллнлового спирта, 100 вес. ч. бензола и 2,2 вес. ч. фосфорной кислоты нагревают при температуре кипени смеси в аппарате с обратным холодильником и Ловушкой до прекращени выделени конденсац110)1ной воды.Example 2. 155 weight. including monometi.tolmelamina. 72 wt. including allnlovogo alcohol, 100 wt. including benzene and 2.2 wt. Part of the phosphoric acid is heated at the boiling point of the mixture in a reflux condenser and a trap until the evolution of condensation 110 1 of water is stopped.
Получаемые продукты при пзвестн1)1х слови х могут непосредственно служить раствором дл пропитывани различных 1а.полннтелей, также материалом дл покрытий; в этих случа х нет необходимости выдел ть их из реакционной с.меси.The products obtained, with well-known 1x words, can directly serve as a solution for impregnating various 1a fillers, also as a coating material; in these cases it is not necessary to isolate them from the reaction mixture.
