Abstract
The present invention relates to a kind of preparation method of surfactant, the preparation method of non-ionic surface agent particularly, it is a raw material with oil tea saponin, rosin, ethanol (or methyl alcohol), hydrochloric acid (or sulfuric acid) etc., the non-ionic surface active agent of synthetic a kind of new yellow-white resin shape crystalline solid.This product can be used for industrial circles such as papermaking, process hides, textile printing and dyeing, chemical industry, agricultural chemicals.This method production safety is reliable, equipment is simple, and raw material are easy to get, and have favorable economic benefit, helps the comprehensive development and utilization of China's cake of camellia oleifera seeds especially.
Description
The present invention relates to a kind of preparation method of non-ionic surface active agent, particularly a kind of is raw material with oil tea saponin, rosin, ethanol (or methyl alcohol), hydrochloric acid etc., prepares a kind of method of new non-ionic surface active agent.
In recent years, more domestic units had carried out the comprehensive utilizating research and the test of cake of camellia oleifera seeds and tealeaves seed.As tealeaves research institute of the Chinese Academy of Agricultural Sciences, institute of Hunan Province's grain section, Guangxi Hechi oil chemistry factory etc., from oleifera dry cake, extract the oil tea saponin slurry, wherein contain oil tea saponin 30～40%, it has good foaming characteristic and detergency, and is used to make shampoo and remover etc.Oil tea saponin and tealeaves seed saponin that the used tealeaves seed saponin of the Chinese Academy of Agricultural Sciences's Hangzhou Theaceae emulsification paraffin wax (Wood-based Panel Production) therefrom extracts are used to prepare shampoo or remover, are not the preparation activating agents.
The present invention is to be raw material with oil tea saponin, rosin (or abietic anhydride), ethanol or methyl alcohol are solvent, hydrochloric acid or sulfuric acid are that catalyst is under 75～80 ℃ of temperature, stirring reaction is about 1.5 hours in reactor, leave standstill then and carry out crystallisation by cooling more than 8 hours, yellow resin-like crystallization is a kind of new non-ionic surface active agent.
Because oil tea saponin is by (known seven kinds at present in multiple triterpenoid saponin unit, be tea sapogenol A, B, C, D, E and magnificent tea soap unit B, D) with the mixture of structure sugar, the formed complex compound of structure acid, therefore, chemical reaction of the present invention is also complicated, its chemical reaction mechanism remains further to study and inquire into, and the reaction equation of one of them is:
One of (rosin acid) oil tea soap unit (non-ionic surface active agent)
The preparation process of described surfactant is: be tea Saponaria officinalis alcohol with oil tea saponin through acid hydrolysis at first, mix with rosin acid (or abietic anhydride) again, make solvent with ethanol or methyl alcohol, carry out esterification reaction under acidity stirring and heating condition, one of products therefrom is a kind of non-ionic surface active agent.The weight ratio that feeds intake of the ripe rosin of oil tea saponin, ethanol (or methyl alcohol), hydrochloric acid (or sulfuric acid) is 1: 0.6: 1: 0.1.And require the oil tea saponin slurry to contain saponin more than 35%, and water is below 3%, and concentration of alcohol is more than 95%.
Two embodiment of the present invention below are provided:
Embodiment one:
Saponin slurry 200 grams that take by weighing oil-containing theasapogenin 46% are put into 100 milliliters of there-necked flasks that electric mixer is housed, industrial alcohol 200 grams of adding 95%, 15 milliliters of 36% hydrochloric acid, add colophony powder 120 grams after crushed again, place heating (to 40～80 ℃) startup stirring on the electric hot water bath, react after 1.5 hours, reactant liquor is moved in 1000 ml beakers while hot, leave standstill 8 hours crystallisation by cooling, take out crystallization and promptly get a kind of non-ionic surface active agent.The surplus liquid of this reaction can be made Recycling Mother Solution and use.
Embodiment two
Take by weighing oil tea saponin slurry 40 grams that contain saponin 30% and put into 250 milliliters beaker, 2 milliliters of hydrochloric acid that add 40 milliliters of 95% industrial alcohol and 36%, add colophony powder 15 grams then, put and be heated to 40～80 ℃ on the water-bath, with the continuous stirring reaction of glass bar 1.5 hours, leave standstill crystallisation by cooling more than 8 hours, this crystalline solid is non-ionic surface active agent of the present invention.Surplus liquid is reusable.
The prepared non-ionic surface active agent of the present invention is yellow-white resin shape crystalline solid, and it will have widely purposes at aspects such as papermaking, leather, textile printing and dyeing, chemical industry, agricultural chemicals. The method production safety is reliable, and raw material is easy to get, and equipment is simple, and cost is low, has preferably economic benefit, is particularly conducive to the comprehensive utilization of China's cake of camellia oleifera seeds.
Claims (3)
1, the present invention relates to a kind of preparation method of surfactant, a kind of preparation method of non-ionic surface active agent particularly, it is characterized in that: be initiation material with the oil tea saponin, oil tea saponin and rosin are dissolved in ethanol or methyl alcohol, with hydrochloric acid or sulfuric acid is catalyst, and under 40～80 ℃ of temperature, stirring reaction is about 1.5 hours, leave standstill crystallisation by cooling, the non-ionic surface active agent of gained yellow-white crystalline solid.
2, in accordance with the method for claim 1, it is characterized in that oil tea saponin is after oleifera dry cake leaches Residual oil with solvent naphtha, is the solvent lixiviate with ethanol again, the leaching liquor simmer down to contains the saponin slurry of oil tea saponin 35% above moisture content below 3%, used rosin is ripe rosin, and ethanol content is more than 95%.
3, by claim 1 or 2 described methods, the weight ratio that feeds intake of oil tea saponin, ripe rosin, ethanol (or methyl alcohol), hydrochloric acid (or sulfuric acid) is 1: 0.6: 1: 0.1.
