Abstract
A continuous rectification process for eucalyptus oil includes pre-treating raw eucalyptus oi lby treating agent and continuous rectification through two rectifying towers with integral stainless steel filler corrugated to obtin medicine-grade or perfume-grade eucalyptus oil.
Description
The present invention relates to a kind of volatile oil extracted from eucalyptus' leaves or twigs purification techniques, specifically a kind of with the processing method of thick volatile oil extracted from eucalyptus' leaves or twigs through continuous rectification processed finished products oil.
Volatile oil extracted from eucalyptus' leaves or twigs extracts from eucalyptus leaves, and eucalyptus is an aiphyllium, contains perfume oil in the leaf, and the main component of volatile oil extracted from eucalyptus' leaves or twigs is a cineole 1.8, and it is having been widely used aspect medicine industry and the perfume industry.
In the present prior art, refining volatile oil extracted from eucalyptus' leaves or twigs majority is to adopt the rectifying of Raschig ring packing tower, batch production technology, and 1500 kilograms of still chargings, the processing cycle is 100 hours, throughput is low.The thick volatile oil extracted from eucalyptus' leaves or twigs of raw material is unprocessed, and Raschig ring is bonded to piece because of the throw out that produces in the rectifying, not only influences rectification effect, and cleans very difficulty, and labour intensity is big.
The object of the present invention is to provide a kind of volatile oil extracted from eucalyptus' leaves or twigs quality product that improves, the continuous rectificating technique of enhancing productivity.
The object of the present invention is achieved like this: earlier the thick volatile oil extracted from eucalyptus' leaves or twigs of raw material is carried out pre-treatment, generate sedimentary white mass in the rectifying easily to remove, prevent that these throw outs from stopping up filler, the steps include: the thick volatile oil extracted from eucalyptus' leaves or twigs of raw material is squeezed in the autoclave pressure, and add a certain amount of treatment agent, and as: water vapor, N
2, CO
2Rare gas element.Thick volatile oil extracted from eucalyptus' leaves or twigs is heated to 100～250 ℃, is 2～10kg/cm at pressure
2State kept 1～5 hour down, and cooling then after filtration or sedimentary method, is removed white depositions.
To carry out rectifying by two continuous rectifying towers through pretreated volatile oil extracted from eucalyptus' leaves or twigs.Rectifying tower (I) is for being equipped with the continuous rectifying tower of the whole filler of stainless steel ripple, and decompression is operated down, and reboiler is adopted the thermal siphon natural circulation and risen cineole 1.8 content＜1.0% in film reboiler, the rectifying requirement overhead distillate; Bottom product consists of cineole 1.8 content 〉=58%, and with this raw material as rectifying tower (II).Rectifying tower (II) also is the continuous rectifying tower that the whole filler of stainless steel ripple is housed, operation under reduced pressure, reboiler adopts the pump circulation falling-film evaporator, regulate the operational condition of rectifying tower (II), can obtain pharmaceutical grade or the spices level volatile oil extracted from eucalyptus' leaves or twigs that content is respectively 70% or 80% cineole 1.8 from tower (II) distillate.
The thick volatile oil extracted from eucalyptus' leaves or twigs of raw material that the present invention is used, wherein the quality of cineole 1.8 is 34～40%.
According to the present invention, the technology specific embodiments of above-mentioned continuous rectification is further described.The operational condition of tower (I): inlet amount is 100～200 liters/hour, 80～90 ℃ of cat head service temperatures; The cat head working pressure is-0.01～0～0.015Mpa; 40～70 liters/hour of cat head liquid outlet quantity, cineole 1.8 content＜1.0%, cineole 1.8 content are about 60% in the bottom product, the operational condition of tower (II), inlet amount is 60～120 liters/hour, 80～100 ℃ of cat head service temperatures, and cat head working pressure-0.006～-0.01Mpa, cat head distillates the finished product volatile oil extracted from eucalyptus' leaves or twigs, cineole 1.8 content 70～83%.
The present invention is owing to carried out pre-treatment to the thick volatile oil extracted from eucalyptus' leaves or twigs of raw material, solved and occurred the problem that throw out stops up filler after volatile oil extracted from eucalyptus' leaves or twigs is heated, because production technique is simple and easy, operational condition is looser, mass transfer effect is good during operation, and the material treatment capacity is big, conserve energy, thereby the cost of product is low, the quality homogeneous, the yield rate height.
The specific embodiments of the invention reaction conditions sees Table 1.
