Abstract
The present invention discloses a kind of method of separating-purifying firpene from turps, the method is the waste heat of character and the rosin distillation generation utilizing α-pinene, beta-pinene, kautschin, longifolene boiling point different in rosin production process, three partial condensation towers are set, then be separated respectively by turps spraying technique and the temperature that controls the outlet of three partial condensation towers and obtain longifolene, α-pinene, beta-pinene, kautschin, thus do not need to increase complete rectifying device in addition terebinthine each composition is purified.Wherein, by separating and purifying method of the present invention, the purity of the finished product α-pinene obtained reaches more than 90%, and the purity of beta-pinene reaches more than 80%, and the purity of kautschin is to more than 90%.
Description
Technical field
The present invention relates to compound separation purification techniques field, particularly relate to a kind of method of separating-purifying firpene from turps.
Background technology
In rosin production process, the generation of turpentine wet goods by product can be attended by.Wherein, terebinthine main component is firpene, and this firpene mainly α-pinene, beta-pinene, but because its rosin production raw material rosin period of storage is long, its turps main component α-pinene generated, beta-pinene generation isomery, particularly α-pinene isomery becomes kautschin, thus make turps main component α-pinene, beta-pinene content reduces, do not reach " GB/T12901-2006 gum turpentine " first grade (alpha+beta firpene content >=80%) quality index requirement, thus make to be difficult to obtain highly purified α-pinene from this turps according to traditional separating and extracting method, beta-pinene.
From turps, the traditional technology of separating-purifying firpene is: the thick oil of the by product obtained in rosin production process---turps enters distillation tower evaporation backflow after clarification, filtration preheating, α-pinene is obtained after water cooler refrigerated separation, still raffinate is beta-pinene, two penta rare and longifolene mixed solution, be separated through distillation tower again, obtain pure beta-pinene; Be separated through distillation tower respectively again and obtain two penta rare, pure longifolene.
If carry out the thick oily purification firpene composition of turps by this flow process, need increase complete rectifying device, repeat distillation and realize, costly, production energy consumption is large, and production cost is also high in such facility investment.
Summary of the invention
The invention provides a kind of method of separating-purifying firpene from turps, the method facility investment expense is few, production cost is low.
In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is:
A method for separating-purifying firpene from turps, the method comprises the following steps:
A. rosin liquid is put into distillation tower and carry out the distillation of rosin one-level, obtain the thick oil of turps and rosin crude product respectively; Wherein, rosin crude product is by obtaining rosin finished product after rectifying;
B. the thick oil of turps steps A obtained passes into partial condensation tower I while hot and carries out fractional condensation, and the temperature in described partial condensation tower I exports controls, at 176 DEG C ~ 178 DEG C, to obtain light constituent I and heavy constituent I; Wherein, this heavy constituent I is passed into the water separator I that deoils to carry out oily water separation and obtain longifolene;
C. the light constituent I obtained by step B passes in partial condensation tower II and carries out further fractional condensation, and the temperature in described partial condensation tower II controls, at 155 DEG C ~ 156 DEG C, to obtain light constituent II and heavy constituent II; Wherein, light constituent II pass into after overcooling fuel and vapor separator II carry out oily vapour be separated obtain α-pinene;
D. the heavy constituent II obtained by step C passes in partial condensation tower III carries out fractional condensation again, and the temperature in described partial condensation tower III controls, at 162 DEG C ~ 163 DEG C, to obtain light constituent III and heavy constituent III; Wherein, this heavy constituent III pass into fuel and vapor separator carry out oily vapour be separated obtain kautschin, light constituent III pass into after overcooling fuel and vapor separator carry out oily vapour be separated obtain beta-pinene.
Owing to adopting technique scheme, the beneficial effect that the present invention obtains is:
The present invention proposes the waste heat of character and the rosin distillation generation utilizing α-pinene, beta-pinene, kautschin, longifolene boiling point different in rosin production process, three partial condensation towers are set, then be separated respectively by turps spraying technique and the temperature that controls the outlet of three partial condensation towers and obtain longifolene, α-pinene, beta-pinene, kautschin, thus do not need to increase complete rectifying device in addition terebinthine each composition is purified; Wherein, by the present invention, the purity of the finished product α-pinene obtained reaches more than 90%, and the purity of beta-pinene reaches more than 80%, and the purity of kautschin is to more than 90%.
