Description

Изобретение касаетс  способа раздельного извлечени  канифоли и высокоплавкой окисленной смолы из еловой или сосновой серки с применением в качестве растворител  древесно-смол ных масел.The invention relates to a method for the separate extraction of rosin and a high-melting oxidized resin from spruce or pine sulfur, using wood-resin oils as a solvent.

Поэтому в предлагаемом способе исключено применение при экстракционной обработке серки весьма огнеопасного растворител  - бензина - и в качестве его заменител  использованы нейтральные смол ные масла. Как установлено, эти масла, при обработке ими богатых окисленными соединени ми естественных смол, при температурах ниже 100° С, обладают известными селективными свойствами.Therefore, in the proposed method, the use of a highly flammable solvent — gasoline — is used in the extraction processing of sulfur and neutral resin oils are used as its substitute. It has been established that these oils, when they are processed with natural resins rich in oxidized compounds, at temperatures below 100 ° C, possess certain selective properties.

Сущность предлагаемого способа заключаетс  в том, что еловую или сосновую серку сначала подвергают экстракции при температуре ниже 100° С - преимущественно при температурах 25-60° С - нейтральными смол ными маслами («холодна  экстракци ), а затем - теми же нейтральными смол ными маслами при температуре кипени  раствора, обычно выще 100° С («гор ча  экстракци ). В процессе «гор чей экстракции дл  усилени The essence of the proposed method is that the fir or pine cherk is first subjected to extraction at a temperature below 100 ° C — mainly at temperatures of 25–60 ° C — neutral resin oils (“cold extraction”), and then the same neutral resin oils at the boiling point of the solution, usually above 100 ° C ("hot extraction). In the process of "hot extraction to enhance

раствор ющих свойств нейтральных смол ных масел можно добавить некоторое количество бутанола, примерно 15-30Vo.Some butanol can be added to the dissolving properties of neutral resinous oils, approximately 15-30Vo.

При «холодной экстракции скипидар и нормальные смол ные кислоты в основном переход т в раствор . Полученный при этом экстракт уваривают на еловую канифоль.In the case of "cold extraction, turpentine and normal resin acids generally pass into solution. The extract obtained is boiled down to fir rosin.

Остаток еерки от «холодной экстракции, обогащенный окисленными соединени ми, экстрагирует при температуре кипени  раствора с нейтральными смол ными маслами или смесью их с бутанолом.The residue from cold extraction, enriched in oxidized compounds, is extracted at the boiling point of the solution with neutral resinous oils or their mixture with butanol.

Из раствора окисленных соединений в нейтральных смол ных маслах растворитель тщательно отгон ют с вод ным паром. Полученную в результате этой операции смолу в расплавленном состо нии подвергают нродувке гор чим или холодным воздухом до тех пор, пока конечный продукт не будет обладать необходимыми качественными показател ми.From the solution of oxidized compounds in neutral resin oils, the solvent is carefully distilled off with water vapor. The resin obtained as a result of this operation in a molten state is subjected to nusavodke by hot or cold air until the final product will not have the necessary quality indicators.

Конечный продукт представл ет собой высокоплавкую смолу темного цвета, в тонком слое прозрачную и имеющую красноватую окраску. Смола обладает высокой темпераThe final product is a dark-melted high-melting resin, transparent and reddish in a thin layer. The resin has a high tempera
