Abstract
The invention discloses a rubber removal method for rubber tree seed oil. The method includes: mixing a rubber removal agent with rubber tree seed crude oil in a mass ratio of 1:2-1:2.5, with the rubber removal agent being an isopropyl alcohol solution with a water content of 0-5wt%; then heating the mixed solution of the rubber removal agent-rubber tree seed crude oil to 50-60DEG C, and conducting stirring at a speed of 10rpm for 5min, then performing heat preservation standing for 40-60min to obtain a supernatant and precipitate, then subjecting the supernatant to pressure reduction distillation, and recovering the rubber removal agent, thus obtaining the rubber removed rubber tree seed oil. The method provided by the invention can achieve complete rubber removal of rubber tree seed oil, can well reduce crude oil loss, also the rubber removal agent has small toxicity, and the obtained rubber tree seed oil has good quality.
Description
Technical field
The present invention relates to the method for a kind of seeds of rubber tree oil removing rubber.
Background technology
Seeds of rubber tree oil crude oil is through the vegetables oil that squeezing process is produced from the seed benevolence of rubber tree, has been widely used in edible, industry and the industry tool such as medical.
Containing abundant unsaturated fatty acids in seeds of rubber tree oil, wherein the serial linolic acid of ω-6 and the serial linolenic acid content of ω-3 are up to more than 60%, are that a kind of nutrition-allocated proportion is reasonable, have the vegetables oil of edible and healthy function.But the rubber in seeds of rubber tree oil crude oil is the principal element that restriction seeds of rubber tree oil eats, although it is to the effect of human non-toxic's evil, rubber can affect the quality of edible seeds of rubber tree oil.
Existing patent of invention 200910094034 " method and apparatus of removing rubber from rubber seed oil " relates to the method for seeds of rubber tree oil removing rubber at present, the method is come unstuck with acetone, acetone is mixed according to volume 1:1 ~ 1:1.5 by heavy adhesive dispenser with rubber seed crude oil, be heated to 50 ~ 60 DEG C, leave standstill 40 ~ 60 minutes, rubber can be precipitated out from rubber seed crude oil.But acetone is the malicious reagent of a kind of easily system, and public security department's control is strict, is unfavorable for that enterprise produces.Moreover acetone toxicity is large, has paralysis effect to human central nervous system, and acetone boiling point low (being about 56.5 DEG C), in actual mechanical process, molten consumption is large, can increase production cost, reduces production security.
Therefore, be necessary to make further improvements the method for the existing natural rubber removed in seeds of rubber tree oil.
Summary of the invention
For thoroughly removing the natural rubber in seeds of rubber tree oil, the invention provides the method for a kind of seeds of rubber tree oil removing rubber, to adapt to actual production demand, enhancing productivity, reducing production cost.
In order to reach above-mentioned target of the present invention, the present invention is achieved through the following technical solutions: a kind of method of seeds of rubber tree oil removing rubber, through the following step: removing rubber agent mixed for 1:2 ~ 1:2.5 in mass ratio with seeds of rubber tree crude oil, described removing rubber agent is the aqueous isopropanol of water content 0 ~ 5wt%; Again the mixed solution of removing rubber agent-seeds of rubber tree crude oil is heated to 50 ~ 60 DEG C, and carry out stirring 5 minutes with the speed of per minute 10 turns, then insulation leaves standstill 40 ~ 60 minutes, obtain upper liquid and precipitation, again by upper liquid through underpressure distillation, reclaim removing rubber agent, namely obtain the oil of the seeds of rubber tree after removing rubber.
Described precipitation and removing rubber agent are after 1:1 ~ 1:1.5 mixes in mass ratio, stirring 5 minutes is carried out at 50 ~ 60 DEG C, while precipitation (rubber) agitator treating, the seeds of rubber tree oil remained thoroughly is come unstuck, again after solid-liquid separation, carry out underpressure distillation to liquid portion, reclaim removing rubber agent, the seeds of rubber tree after residuum and removing rubber is oily to be merged.
The temperature of described underpressure distillation is 80 DEG C, pressure is 0.01MPa.
Described recovery gained removing rubber agent energy Reusability, water content can increase gradually (water transport in seeds of rubber tree crude oil is in removing rubber agent), just need to dewater to removing rubber agent, until the water content of removing rubber agent is 0 ~ 5wt%, flow through dehydration column by removing rubber agent, in dehydration column, fill anhydrous sodium carbonate or calcium oxide.
The present invention adopts Virahol as removing rubber solvent, and compared with acetone, Virahol toxicity is little, does not belong to easily poison product processed, is easy to get.Virahol boiling point is 82.45 DEG C, and molten consumption is low compared with acetone, obviously can reduce production cost.And Virahol is after mixing with seeds of rubber tree crude oil, increase the polarity of grease, seeds of rubber tree crude oil (triglyceride level and lipid acid) and removing rubber agent are dissolved mutually, but dissolves in the nonpolar natural rubber solution that can not increase in this polarity, and then assemble, separate out.Method of the present invention is thorough to seeds of rubber tree oil removing rubber, and can reduce oil loss well, and removing rubber agent toxicity is little, the seeds of rubber tree oil quality obtained is good.
