Description
Термореактивиые смолы, способные на холоду или при нагревании; переходить в неплавкие продукты, предлагаетс получ.ать в две стадии по Сотедующему способу. В первой стадии процесса конденсируют фенолы с винил ацетатом или монохлорвинилацетатом в присутствии нефт ных сульфокислот. При соответствуюндих соотношени х образование смОоТы происходит при комнатной температуре.Thermo reactive resins, capable of cold or heat; it is suggested to get into non-meltable products in two stages using the Setiuu method. In the first stage of the process, phenols are condensed with vinyl acetate or monochlorovinyl acetate in the presence of petroleum sulfonic acids. With appropriate ratios, the formation of cmoots occurs at room temperature.
При эквимолекул рных соотношени х вин1 лацетата и фенола в присутстЕ .ии указанных сульфокислот получаютс термоплавкне смолы.With equimolecular ratios of vin1 latex and phenol in the presence of these sulfonic acids, a hot melt resin is obtained.
При воздействии на получение термоплавкне смолы альдегидов, нагфимер формальдегида, гексаметилентетрамина, уксустюго альдегида, фурфурола или бензойного альдегида, получаютс тёрмореактивные смолы, нереход н 1:ие при обыкновенной темиературе или при нагреваиии в ненлавкое нерастворимое состо ние.When exposed to the production of a thermoplastic resin, aldehydes, formaldehyde nagfimer, hexamethylenetetramine, acetaldehyde, furfural, or benzoic aldehyde, are obtained thermosetting resins, uninterrupted: 1, with ordinary temperature or heating, a non-soluble gum will dissolve.
Такие же термореактивные смолы получить путем воздейстЕи винилацетата или монохлорвииилацетата на новолачные смолыв присутствии вын1еуказанных сульфокислот.To obtain the same thermosetting resins by subjecting vinyl acetate or monochloroyl acetate to novolac resins in the presence of the indicated sulfonic acids.
Пример I. 1 моль фенола и 1 моль виинлацетата конденсируют при комнатной температуре в присутствии 5-10% нефт ных сульфокнслот «Контакт. Выход смол около 200% на фе1ю;г. Дл получени термореактивных, отверждаюш.ихс смол добавл ют 40-60% от вз того фенола альдегидов или соответствующее количество гексаметилентетрамина . Полученный продукт можно использовать дл получени склеивающих средств, импрегнации и дл литых или прессовочных изделий .Example I. 1 mole of phenol and 1 mole of vinylacetate are condensed at room temperature in the presence of 5-10% oil sulfo acids “Contact. Resin yield of about 200% at fe; 40-60% of the taken phenol aldehydes or the corresponding amount of hexamethylenetetramine is added to obtain thermosetting, cured resin. The resulting product can be used for the preparation of adhesives, impregnation and for cast or molding products.
Пример П. Новолачна смола, полученна конденсацией 7 моль фенола с 8 моль формальдегида в присутствии 5% нефт ных сульфокислот «Контакт дополнительной обработкой 20-30% випилацетата при нагревании до 60-80°, переводитс в неплавкий и нерастворимый продукт типа фенольного резита.Example P. Novolac resin obtained by condensation of 7 moles of phenol with 8 moles of formaldehyde in the presence of 5% petroleum sulfonic acids. Contact by additional treatment with 20-30% vipylacetate when heated to 60-80 ° C translates into a non-meltable and insoluble type of phenol resit.
Пример HI. Новолачную смолу, полученную конденсацией 2 л-1оль фенола и 1 лю. формальдегида, в присутствии 20-30% от веса фенола нефт ных сульфокислот «Контакт, перевод т в термореактивную смолу, а зиачит в неплавкий и нерастворимый продукт типа феноль-иого резита, при дополнительной обработке 40-60% винилацетата.HI example. Novolac resin obtained by condensation of 2 l-1 mol of phenol and 1 lu. formaldehyde, in the presence of 20–30% by weight of phenol from petroleum sulfonic acids “Contact, is transferred to a thermosetting resin, and it is cast in a non-meltable and insoluble type of phenol resite, with additional treatment with 40–60% vinyl acetate.
