Description

в промышленности искусственных смол и пластмасс одним из наиболее распространенных классов смол  вл ютс  продукты, получающиес  путем конденсации фенолов или аминов с альдегидами, главным образом, с формальдегидом .In the industry of artificial resins and plastics, one of the most common classes of resins are products obtained by the condensation of phenols or amines with aldehydes, mainly formaldehyde.

Широкое распространение смол этого класса лимитируетс  дефицитностью формальдегида и дороговизной последнего.The wide distribution of resins of this class is limited by the scarcity of formaldehyde and the high cost of the latter.

Произведенными авторами насто щего изобретени  опытами доказано, что искусственные смолы могут быть приготовлены путем конденсации аминов , фенолов или фенолсодержащих продуктов с жидкостью, получающейс  при окислении органических веществ по методу холодного пламени, описанному в авторском свидетельстве N° 51180.Experiments made by the authors of the present invention have shown that artificial resins can be prepared by condensing amines, phenols or phenol-containing products with a liquid obtained by oxidizing organic substances using the cold flame method described in copyright certificate No. 51180.

Предлагаемый способ значительно расшир ет сырьевую базу и снижает стоимость смолы благодар  замене дорогого альдегидного компонента более дешевым продуктом.The proposed method significantly expands the raw material base and reduces the cost of the resin by replacing the expensive aldehyde component with a cheaper product.

Конденсаци  идет с добавкой основных или кислых катализаторов, а также и без добавки. В последнемCondensation comes with the addition of basic or acidic catalysts, as well as without addition. In the last

случае конденсаци  происходит под вли нием органических кислот, содержащихс  в продуктах, полученных по методу холодного пламени.In the event of condensation, it occurs under the influence of organic acids contained in products obtained by the cold flame method.

Получающиес  смолы могут быть использованы дл  приготовлени  лаков , а также дл  изготовлени  пластических масс, причем могут примен тьс  различные наполнители.The resulting resins can be used to prepare varnishes, as well as to make plastics, and various fillers can be used.

Органические вещества (спирты, эфиры и т. д.), содержащиес  в продуктах , полученных по методу холодного пламени и не вступающие в конденсацию , могут быть регенерированы путем охлаждени  паров, выдел ющихс  при сушке смолы, и использованы дл  различных целей.Organic matter (alcohols, ethers, etc.) contained in cold-flame products that do not condense can be regenerated by cooling the vapors evolved when the resin is dried and used for various purposes.

Пример. Вз то 250 г фенола и 330 г продуктов, полученных по методу холодного пламени из пропиленовой фракции отходов крэкингбеизина , содержащей 17% альдегидов . Конденсаци  производилась в колбе на вод ной бане в присутствии 2/о сольной кислоты удельного веса 1Л9. Нагревание продолжалось до прекращени  увеличени  объема водного сло , после чего водный слой был отделен и смола была высушенаExample. For example, 250 g of phenol and 330 g of products obtained by the cold flame method from the propylene fraction of crackingbeisin waste containing 17% aldehydes. Condensation was carried out in a flask on a water bath in the presence of 2 / с of solo acid of specific gravity 1L9. Heating continued until the increase in volume of the aqueous layer ceased, after which the aqueous layer was separated and the resin was dried.
