The invention discloses a process for producing fatty acid calcium based on a one-step water method, which comprises the following step: mixing a mixture of fatty acid and water with calcium hydroxide or calcium oxide according to a certain ratio, and reacting at a certain temperature for a certain time to obtain fatty acid calcium. The process disclosed by the invention can achieve the purposes of lowering the production cost and improving the production efficiency and product purity.
Description
Technical field
The present invention relates to the production technique of fatty acid calcium, be specifically related to a kind of production technique of using a step water law to produce fatty acid calcium.
Background technology
Fatty acid calcium is a kind of additive commonly used, is used in widely in fodder additives, the stabilizer for plastics.
The method of current production fatty acid calcium has a lot, and method comparatively commonly used is such as being saponification method, scorification or AV method, and the AV method also is called a step dry method.Wherein, scorification be with lipid acid and calcium hydroxide (or quicklime) under the situation that catalyzer and less water exist, under 140-150 ℃ of condition, react, obtain the fatty acid calcium finished product.Use the shortcoming of scorification to be the fatty acid calcium of being produced, free acid content is higher with respect to saponification method, and owing to be pyroreaction, the color and luster of product is wayward, because the fatty acid calcium of producing is a vitreum, discharging is difficulty comparatively simultaneously.
The AV method be with lipid acid and calcium hydroxide (or quicklime) in the situation that catalyzer and less water exist, obtain Powdered calcium stearate thereby vacuumize reaction.The fatty acid calcium free acid that the AV method is produced also is higher with respect to saponification method, and the control condition in the reaction process is harsh relatively, to having relatively high expectations of equipment.
Saponification method is under the situation that water gaging exists greatly, lipid acid is reacted with sodium hydroxide earlier, behind the generation sodium soap; Again calcium chloride is joined and carry out replacement(metathesis)reaction in the sodium soap solution; Obtain fatty acid calcium, then fatty acid calcium is dewatered and drying, obtain finished product.
Use saponification method can produce great amount of wastewater in process of production; Contain a large amount of inorganic salt compositions in the waste water, be unfavorable for recycling, increased production cost; And because the reaction process time is longer; Middle can produce calcium hydroxide, and because the purity tolerances of inorganic salt itself, reduce the purity of product fatty acid calcium.Contain a large amount of cl ionss in addition in the sewage, the water treatment difficulty is strengthened.
Summary of the invention
For solving the problems of the technologies described above, we have proposed the production technique that an a kind of step water law is produced fatty acid calcium, reduce production costs to reach, and enhance productivity and the purpose of product purity.
For achieving the above object, technical scheme of the present invention is following:
The production technique that one step water law is produced fatty acid calcium comprises: make mixture and the calcium hydroxide of lipid acid and water or quicklime react certain hour at a certain temperature according to a certain percentage, obtain fatty acid calcium.
Preferably, also comprise dewatering process, heating process and drying process.
Preferably, said lipid acid is the saturated or unsaturated fatty acidss of long-chain such as Triple Pressed Stearic Acid, oleic acid, palmitinic acid.
Preferably, said certain temperature is 80-100 ℃.
Preferably, said certain hour is 1-3h.
Pass through technique scheme; The present invention directly generates fatty acid calcium through the single step reaction of the lipid acid aqueous solution and calcium hydroxide or quicklime, has improved production efficiency, and does not have intermediate to produce in the reaction process; Improved product gas purity; Do not produce waste water after the reaction simultaneously, resulting reaction water can be reused, and has practiced thrift production cost.
Description of drawings
Fig. 1 is that the disclosed step water law of the embodiment of the invention is produced the schema of the production technique of fatty acid calcium.

3, input calcium hydroxide or quicklime react in the lipid acid aqueous solution, generate fatty acid calcium;
Wherein, the charging capacity of calcium hydroxide or quicklime can be carried out with reference to (13-17) % of lipid acid charging capacity, also can calculate through formula, for example:
Calcium hydroxide consumption=(lipid acid acid number/56100) * [MCa (OH)
2/ 2X]
Here: the lipid acid acid number refers to be used to produce the acid number of the lipid acid of fatty acid calcium; MCa (OH)
2Refer to the molecular weight of calcium hydroxide, can calculate according to 74; X refers to the purity of employed calcium hydroxide.
