Abstract
The invention relates to a preparation method of terpilenol. The preparation method comprises the following steps of: with Alpha-pinene as a raw material, directly synthesizing terpilenol by adopting a one-step method, adding 700-800 parts of industrial Alpha-pinene, 700-800 parts of water, 8-10 parts of sulfuric acid and peregal into a reaction tank, carrying out hydration reaction under the temperature of 70-80 DEG C to obtain crude terpilenol and carrying out fractionation to obtain the terpilenol product. The preparation method disclosed by the invention has the characteristics of simple process, short work-flow, easiness for control, high product yield, high quality and the like and can be widely applied to the industries of printing ink, chemical engineering, light engineering, medicines and telecommunication.
Description
Technical field
The invention belongs to a kind of turps deep processing method.
Background technology
Turps is the terpene blend that monoterpene and sesquiterpene form, wherein with α-pinene content for the highest.This product is mainly used in synthetic perfume, camphor, borneol, terpine resin, sterilant, hormone, repellent, air freshener, advanced lubrication wet goods, its sintetics reaches kind more than 1000, and turps has become the important regenerative raw materials source of fine chemical product at present.Turps is the liquid that clear, colorless has aromatising flavour, and relative density is 0.86～0.87, and refractive index is 1.4670～1.4710.The organic solvents such as turps and ether, alcohol, benzene, dithiocarbonic anhydride, tetracol phenixin dissolve each other.Turps itself is no acidic, but is subjected to extraneous oxygenizement to form free acid.Contain acid and affect color owing to moisture, if anhydrous, anacidity again not with contact with air, then not easy to change.Turps is water insoluble, but volatile drying.Belong to the secondary inflammable liquid, 32 ℃ of flash-points, 235 ℃ of spontaneous ignition temperatures.Meet high hot explosive, meeting strong oxidizer also can combustion explosion, and limits of explosion is 0.8～62 percent by volume in the time of 32～53 ℃.Turps is a kind of natural essential oil, is take the mixture of firpene as main multiple terpene hydro carbons, and distinctive chemically reactive is arranged, and is coating, artificial camphor, Terpineol 350, synthetic perfume, medicine, synthetic resins, the aspect industrial chemicals such as organic chemical industry.A-firpene and b-firpene in the synthetic perfume turps can synthesize multiple spices, phantol, mentha camphor, geranial, jononeionone, and sandenol etc., to replenish the deficiency of natural essential oil, prevailing is Terpineol 350.Owing to have the Syringa oblata Lindl. flavor, its manthanoate and acetic ester can be used for the essence preparation, are used for senior solvent and deodorizing agent.Also being used for medicine, agricultural chemicals, plastics, soap, printing ink industry, is again the solvent of color on the glassware.Through Chinese publication retrieval, find 416 of relevant patents of invention, 64 of utility model patents the scheme identical with present patent application of not finding.
Summary of the invention
Purpose of the present invention is: propose a kind of Terpineol 350 preparation method.
Terpineol 350 preparation method of the present invention is characterized in that: take α-pinene as raw material, single stage method is synthetic Terpineol 350 directly, by weight, proportioning raw materials is: 700-800 parts of industrial α-pinenes, 700-800 parts in water, 8-10 parts in 98% sulfuric acid, 1-2 parts of peregal emulsifying agents, its processing step is: with 700-800 parts of industrial α-pinenes, 700-800 parts in water, 8-10 parts in sulfuric acid, peregal adds in the retort, carries out hydration reaction under 70-80 ℃, leaves standstill crystallization, separate residual acid, washing adds the alkali neutralization, washing, dehydration, get thick Terpineol 350, thick Terpineol 350 namely gets the Terpineol 350 product through fractionation.
The present invention's beneficial effect compared with prior art: the characteristics such as it is short to have a technique quick-reading flow sheets, is easy to control, and the product yield is high, and quality is good, general being applied in printing ink, chemical industry, light industry, medicine and the telecommunication industry.Be suitable for the preparation perfumed soap, makeup and spices also are to print good molten Ji color on iron sheet, the glassware, and the Terpineol 350 of lower concentration is used as flotation agent, sterilizing agent and clean-out system.
