Description

Прр-длагаемый способ предусматривает получение осветленной еловой канифоли и обиетиновой смолы из еловой серки или живицы.The proposed method involves obtaining clarified spruce rosin and an obieten resin from spruce or resin.

Известные способы переработки еловой серки и живицы основаны на обработке их органическими растворител ми.Known methods of processing spruce and resin are based on the processing of organic solvents.

Отличие предлагаемого способа заключаетс  в том, что обработку ведут вначале бензином, а затем фурфуроло.м.The difference of the proposed method lies in the fact that the treatment is carried out first with gasoline, and then furfurol.m.

Пример. 100 частей серки (содержащей до 60% смолистых веществ ) при перемешивании обрабатывают 170 част ми бензина «галоща . Операцию повтор ют три раза и все получающиес  при этом бензиновые растворы сливают вместе.Example. 100 parts of sulfur (containing up to 60% of resinous substances) with stirring are treated with 170 parts of gasoline tare. The operation is repeated three times and all the resulting gasoline solutions are drained together.

Затем при перемешивании серку обрабатывают 45 част ми технического фурфурола. Бензиновый и фурфурольиый растворы отфильтровываю1 через нутчфильтры, а затем подвергают взаимной экстракции путем перемешивани  растворов центробежным насосом.Then, with stirring, the sulfur is treated with 45 parts of technical furfural. The gasoline and furfural solutions are filtered out through suction filters, and then subjected to mutual extraction by mixing the solutions with a centrifugal pump.

В противоточной насадочной колонке бензиновый раствор подают снизу, а фурфурольный - сверху.In a countercurrent packed column, a gasoline solution is fed from the bottom, and furfural - from the top.

После отстаивани  бензиновый раствор перемешивают с водой и дают отсто тьс , после чего получают обычными методами 37,5 частей осветленной еловой канифоли, 585 частей бензипа, насыщенного фурфуролом , и 4 части неочищенного скипидара.After settling, the gasoline solution is mixed with water and allowed to stand, after which 37.5 parts of clarified fir rosin, 585 parts of benzip saturated with furfural, and 4 parts of crude turpentine are obtained by conventional methods.

Из фурфурольного раствора упариванием получают 18 ч. обиетиновой смолы, 50 ч. фурфурола, насыщенного бензином и др. компонентами , содержащимис  в еловой серке.From the furfural solution, 18 parts of the obietic resin, 50 parts of the furfural, saturated with gasoline and other components contained in the spruce core are obtained by evaporation.

Регенерированные бензин и фурфурол без дополнительной очистки могут быть использованы дл  проведени  нового цикла.Regenerated gasoline and furfural without further purification can be used to carry out a new cycle.

При переработке еловой живицы таким же образом получают более высокий выход канифоли с повышенным ее качеством и меньпий выход обиетиноБой смолы.In the processing of spruce resin in the same way, a higher yield of rosin with a higher quality and a smaller yield of resin are obtained.

№ 140517- 2 Предмет изобретени No. 140517- 2 Subject of the invention
