Abstract

The invention relates to the technical field of rectification, and discloses a turpentine rectification process. According to the invention, a distillation retort A is used for carrying out primary distillation on turpentine so as to extract alpha-pinene, after the turpentine in the distillation retort A is completely distilled, kettle residues in the distillation retort A can be conveyed into a distillation retort B through a communicating pipe, and the distillation retort B is used for carrying out secondary distillation on the kettle residues in the distillation retort A so as to extract beta-pinene through the distillation retort B. The problems that the production time of alpha-pinene and beta-pinene is increased and the production efficiency is too low due to the fact that turpentine is distilled by a single distillation tower when turpentine is rectified in the prior art are solved, so that when beta-pinene is extracted, the turpentine in a cooling tank A does not need to be pumped out after being cooled, the time required by the production of the beta-pinene can be shortened, and the production efficiency of the alpha-pinene and the beta-pinene is improved.

Description

technical field [0001] The invention relates to the technical field of rectification, in particular to a turpentine rectification process. Background technique [0002] Turpentine is a kind of essential oil. It is an important industrial raw material. Turpentine is a liquid extracted from the resin of coniferous plants by distillation or other methods. The main component is terpene. Turpentine can be mixed with chloroform and ether in any proportion. Or acetic acid mixed, but insoluble in water, turpentine is a high flash point flammable liquid, volatile, will produce a lot of smoke when burning, its main components are α-pinene and β-pinene and a small amount of 1-pinene. [0003] At present, the main means of extracting α-pinene, β-pinene and 1-pinene from turpentine is to carry out rectification to turpentine, when the turpentine is preheated, distilled and then cooled and separated by a cooler, α-pinene can be extracted. Pinene, at this time, the remaining still residue...
