Abstract
A process for refining cubeba kernel oil, which can replace coconut oil used in soap production for low cost, includes such steps as pressing oil, degumming by adding acid, water washing, dewatering, physical decolouring and filter, and features its last additional chemical decolouring with H2O2 and water discharge to further remove colour impurities.
Description
The present invention relates to a kind of mountain grey seed nuclei benevolence oil refining technology, provide for substituting import Oleum Cocois production soap based article.
At present, the production process route of the grey seed nucleolus oil in China China National Light Industrial Products Department Taiyuan daily use chemicals institute development and use mountain is: squeeze nucleolus oil-the add acid smart Fatty acid methyl ester of fatization-esterification-separation of glycerin-wash-dewater-distill-obtain that comes unstuck-give.The main drawback of this technology is: 1, complex manufacturing, facility investment is many, the productive expense height.2, the smart Fatty acid methyl ester of finished product only is applicable to the various tensio-active agents of processing, and uncomfortable as the raw material of producing the soap series products.
The objective of the invention is to provide a kind of mountain grey seed nuclei benevolence oil refining technology, this technology is not only simple, and production cost is low, and the alternative Oleum Cocois of its goods is as the raw material of producing the soap series products.
Mountain of the present invention grey seed nuclei benevolence oil refining technology comprises squeezes nucleolus oil, and add acid and come unstuck, washing, dehydration, physical decolorization and filtration operation is characterized in that, continue to adopt hydrogen peroxide to carry out chemical decolorization to the grey seed in mountain after the above-mentioned operation processing and handle draining at last.
In above-mentioned technology because after carrying out physical decolorization by the adsorption of gac, utilize the oxidisability of hydrogen peroxide again, destroy chromophoric group, so the nucleolus oil that this technology makes is transparent, clear, delicate fragrance, alternative part or all of Oleum Cocois is as the raw material of producing the soap series products.
The production technique that the present invention is concrete comprises and squeezes nucleolus oil, adds acid and come unstuck, washing, dehydration, and physical decolorization is filtered and chemical decolorization (draining at last).
Add the sulphuric acid soln that adopts concentration 〉=95% in the sour Degumming Procedures, the consumption of this sulphuric acid soln be the grey seed nucleolus oil in mountain heavy 2～8%, optimum value is 5%.
Adopt salt solution to wash in washing, the dehydration procedure, brine concentration is 3～5%, and temperature is 50～70 ℃, and the pH value that is washed to the grey seed nucleolus oil in mountain reaches 5～7.
Admix gac in the physical decolorization operation, consumption be the grey seed nucleolus oil in mountain heavy 2～6%, vacuum tightness is 500～700mmHg, temperature is 70～85 ℃, the time is 20～40min.
Admixing hydrogen peroxide solution concentration during chemical decolorization is handled is 30%, consumption be the grey seed nucleolus oil in mountain heavy 10～20%, the reaction times is 90min, temperature is 70～100 ℃.
The present invention is by the foreign pigment in physics and the chemical process removal nucleolus oil, making originally, black nucleolus oil is transformed into golden yellow oil transparent, delicate fragrance, and this technology purified nucleolus oil still keeps approaching the effective constituent of Oleum Cocois, thereby alternative import Oleum Cocois is used to make soap series products such as perfumed soap, soap powder, liquid soap, also further deep processing forming surfactants.
Actual production proves through the our factory, adopts above-mentioned technology purified nucleolus oil to substitute the consumption of import Oleum Cocois 1/2, is used to produce high-grade coloured perfumed soap, and the outward appearance of its product and performance are all identical with the product that original employing import Oleum Cocois is produced for batching.
According to statistics, import Oleum Cocois price per ton is about 5,000 yuan at present, and purified nucleolus oil total cost of the present invention has only 3,000 yuan, therefore, use the import Oleum Cocois that one ton of purified nucleolus oil of the present invention substitutes a ton, will reduce cost 2,000 yuan, as use the words of kiloton purified nucleolus oil of the present invention, will reduce cost 2,000,000 yuan, its using value is very considerable.
