Description
Предлагаемый способ имеет целые получение продуктов конденсации фенола или его гомологов с альдегидами и применение этих продуктов дл изготовлени лаков.The proposed method has the whole production of condensation products of phenol or its homologues with aldehydes and the use of these products for the manufacture of varnishes.
При конденсации крезолов с формальдегидом в присутствии щелочей получаютс продукты, растворимые лншь в спирте и поэтому не поддающиес смеишванию, напр., со смолами, нерастворимыми в спирте. Спиртовые растворы их могут служить лаками дл покрыти металлов прн нагревании, но они не пригодны дл покрыти эластичных предметов, напр., фибры, тонкого железа, брезента, картона и т. п.By condensation of cresols with formaldehyde in the presence of alkalis, products are soluble in alcohol and therefore not susceptible to mixing, for example, with alcohol insoluble resins. Alcohol solutions of them can serve as lacquers for coating metals by heating, but they are not suitable for coating elastic objects, for example, fiber, thin iron, tarpaulin, cardboard, etc.
Автором установлено, что если конденсацию вести в присутствии уксуснокислого свинца, то получаетс продукт, растворимый и в спирту и в бензоле, смешивающийс с обычными смолами и дающий при нагревании твердые, но эластичные покровы.The author has found that if condensation is carried out in the presence of lead acetate, then a product is obtained that is soluble in both alcohol and benzene, which is mixed with conventional resins and gives hard but elastic coatings when heated.
Пример.Example.
100 частей крезоловой кислоты, 130 „ 40% формалина,100 parts of cresolic acid, 130 „40% formalin,
15 „ уксуснокислого свинца. Все нагревают до кипени и сосуде с холодильником; после того, как наступит момент конденсации (густа , затвердевающа масса), нагревание оканчивают , лак отдел ют от водного сло и уваривают до желаемой густоты.15 lead acetate. Everything is heated to a boil and in a refrigerator; after the moment of condensation (thick, hardening mass), the heating is terminated, the lacquer is separated from the aqueous layer and boiled to the desired thickness.
ПРЕДМЕТ ИЗОБРЕТЕНИЯ.SUBJECT OF INVENTION.
1.Способ получени продуктов конденсации фенола или его гомологов с альдегидами, отличающийс тем, что фенол или его гомологи нагревают с альдегидами в присутствии уксуснокислых солей свинца,1. A method of producing phenol condensation products or its homologues with aldehydes, wherein phenol or its homologs are heated with aldehydes in the presence of lead acetate salts,
2,Применение указанного в п. 1 продукта дл изготовлени лака растворением его в смеси с сбыч) смолами , или без них, в органических растворител х .2, The use of the product indicated in claim 1 for making a varnish by dissolving it in a mixture with sabich) resins, or without them, in organic solvents.
