Abstract
The invention relates to a method for preparing hexadecanoic acid and oleic acid extracted from rice oil distillate, which adopts rice oil distillate as the main raw material and produces a finished product by three steps such as edulcoration, and the like. The method comprises the following steps of selection, saponin elimination, fractionation, fractionation and forming a finished product. The method adopts the technical scheme that the rice oil distillate is adopted as the main raw material to be directly added into a saponin eliminating tower without adding other chemicals, only a high-efficient fractionating tower is adopted, incision and fractionating on hexadecanoic acid, oleic acid, unsaponifiable substances and impurities are carried out to produce a product with multiple functions. The invention overcomes the defects of the traditional preparation method with the complex production technology, high energy consumption, severe pollution to environment and low product quality, and is suitable for producing hexadecanoic acid and oleic acid extracted from rice oil distillate.
Description
Technical field
The present invention relates to a kind of preparation palmitinic acid, oleic method, especially a kind of palmitinic acid, oleic preparation method of from the Rice pollard oil distillment, extracting.
Background technology
Existing rice bran very easily becomes sour when storing, and makes the grease in the rice bran be decomposed into lipid acid.Therefore; The grease that from rice bran, squeezes contains more lipid acid, make Rice pollard oil reach food sanitation standard, often through the acid of molecular distillation weeding of grease fat; Except that containing 70～80% lipid acid, also contain 10～20% unsaponifiables and other impurity in the material that distills.And the major ingredient of lipid acid is palmitinic acid and oleic acid, so, from the Rice pollard oil distillment, remove unsaponifiables and impurity, extract purified lipid acid, again fatty acid separation being become palmitinic acid and oleic acid is a utilize resources synthetically, the effective way that turns waste into wealth.
Summary of the invention
To above-mentioned situation, the object of the present invention is to provide a kind of palmitinic acid, oleic preparation method of from the Rice pollard oil distillment, extracting, it does not add any chemical; Nontoxic non-corrosiveness, readily biodegradable also has technology simple; Operation easily, production cost is low, and output is big; Productive rate is high, and storing safety, raw material sources enrich.
Be the realization above-mentioned purpose, a kind of palmitinic acid, oleic preparation method of from the Rice pollard oil distillment, extracting, it is chosen the Rice pollard oil distillment and makes main raw material, processes product through three-step approaches such as removal of impurities, and its step is following:
I, technical process
Select materials-Tuo soap-fractionation-fractionation-finished product;
II, operation steps
1. choose discarded Rice pollard oil distillment adding and take off Zao Ta, oil is 1:0.002-0.003 with the mass ratio of water vapour in the Rice pollard oil distillment, sloughs the foreign odor flavor with water vapor film removal methods;
The Rice pollard oil distillment that
takes off behind the soap gets into first separation column, fractionates out palmitinic acid from cat head;
The present invention adopts and to choose the Rice pollard oil distillment and make main raw material and directly add and take off Zao Ta, under the situation of not adding other chemical, only adopts efficient separation column; To palmitinic acid, oleic acid, unsaponifiables and impurity cut fractionation, produce the technical scheme of the product of different purposes; Overcome employing traditional preparation process method, its complex manufacturing, energy consumption is high; Environmental pollution is serious, the defective that quality product is low.
Beneficial effect of the present invention:
(I) the present invention is a raw material with the Rice pollard oil distillment, under the situation of not adding other chemical, only adopts efficient separation column, and to palmitinic acid, oleic acid, unsaponifiables and impurity cut fractionation, produce the product of different purposes;
(II) the present invention is a raw material with the Rice pollard oil distillment, and its preparation technology is simple, processing ease, and facility investment is few, and production cost is low, and is with short production cycle, and output is big, and productive rate is high, and raw material sources are wide;
(III) the present invention extracts palmitinic acid, oleic preparation method from the Rice pollard oil distillment, the palmitinic acid (CH3 (CH2) 14COOH) that this preparation method produces, white crystals shape, purity 95～98%; Oleic acid (CH3 (CH2) 7HC=CH (CH2) 7COOH), faint yellow, purity 98%; Unsaponifiables, the black viscous liquid.
(IV) the present invention extracts palmitinic acid, oleic preparation method from the Rice pollard oil distillment, this preparing method's safety is nontoxic, pollution-free; Not loss parts, energy consumption is low, and readily biodegradable is environmentally friendly; Can round-the-clockly use, higher is arranged, flash-point; Belong to non-dangerous goods, storing safety, business potential is huge.
The present invention is fit to from the Rice pollard oil distillment, extract palmitinic acid, oleic production.
Below in conjunction with accompanying drawing and embodiment the present invention is done further detailed explanation.
