Description
Известен р д способов получени пластических масс путем прессовани продуктов частичного гидролиза древесины.A number of methods for producing plastics by pressing the products of partial hydrolysis of wood are known.
При получении пластических масс из частично гидролизованной древесины хвойных пород большое вли ние на их качество оказывают смолистые вещества. Соснова древесина содержит, в среднем, 5% этих веществ. Если в качестве прессовочного порошка примен ть продукт частичного гидролиза древесины, полученный с выходом, равным, 50%, то содержание смолистых веществ возрастет до IQ%, т. е. они станут одним из основных компонентов пресспорощка.Upon receipt of plastics from partially hydrolyzed coniferous woods, resinous substances have a great influence on their quality. Pine wood contains, on average, 5% of these substances. If the product of partial hydrolysis of wood obtained with a yield equal to 50% is used as a pressing powder, the content of resinous substances will increase to IQ%, i.e., they will become one of the main components of the compost.
Найдено, что смолистые вещества, извлекаемые органическими растворител ми из продуктов частичного гидролиза древесины, состо т, в основном , из реакционноспособных смол ных и жирных кислот, в результате гор чего прессовани порошков из гидролизованной древесины , смолистые вещества, содержащиес в них, разлагаютс с выделением значительного количества газов и образованием хррткого твердого остатка, вследствие чего прочность изделий становитс низкой.It has been found that resinous substances, extracted by organic solvents from products of partial hydrolysis of wood, consist mainly of reactive resinous and fatty acids, and as a result of hot pressing of powders from hydrolyzed wood, the resinous substances contained in them decompose with release a significant amount of gases and the formation of a hrtc solid residue, as a result of which the strength of the products becomes low.
Дл повышени прочности предлагаетс перед прессованием пороЩок частично гидролизованной древесины подвергать обработке органическими растворител ми, с целью извлечени из него смол. Экстрагированный таким образом порошок частично гидролизованной древесины прессуют с добавкой фурфурола и анилина или без них.In order to increase the strength, it is proposed to preload the powder pouch of partially hydrolyzed wood with organic solvents in order to extract resins from it. The powder of partially hydrolyzed wood thus extracted is pressed with or without the addition of furfural and aniline.
Пример. Порошок, полученный путем частичного гидролиза измельченной сосновой древесины, разбавленной серной кислотой, был разделен на две части. Одна из них была подвергнута исчерпывающей экстракции, а друга -оставлена без обработки. К обеим част м было добавлено по 8% фурфурола и анилина , без введени дополнительных катализаторов, но с сохранением в порощке кислоты, оставщейс от пресса гидролиза. Отпрессованные издели обладали следующими показател ми:Example. The powder obtained by partial hydrolysis of chopped pine wood, diluted with sulfuric acid, was divided into two parts. One of them was subjected to exhaustive extraction, and the other was left without treatment. 8% of furfural and aniline were added to both parts, without the introduction of additional catalysts, but with the acid remaining in the powder from the hydrolysis press retained. The pressed products had the following characteristics:
