Abstract
The present invention discloses a method for preparing calcium acetate for edible or medical preparations, which comprises the steps of ore material selecting, soaking in acetic acid, filtering, filter pressing, compounding, drying, etc. The product prepared by the method has the advantages of no poison and harmlessness to human bodies, easy absorption, high utilization rate, obvious effect, 27 human body required constant quantity and trace elements, etc.; particularly, the product is ionic calcium salt which can completely dissolve in water solutions, and thus, can be directly absorbed by human bodies, with the absorption rate of 76.3% and the storage rate of 75.6%.
Description
The invention relates to a kind of preparation method of calcium acetate, more particularly about the production method of edible or medical calcium acetate.
Calcium is considerable for human body, calcium be human life this, also be mineral elements maximum in the human body, during hypocalcia, can cause the calcium deficiency syndromes in the human body.At present in the world, most calcium deficiency per capita, the elderly, women, child are particularly serious, the human body calcium deficiency, " calcifames " is a worldwide common problem.
Commercially available calcium agent pharmaceuticals or healthcare products have calcium chloride, calglucon, calcium lactate, secondary calcium phosphate, monocalcium phosphate, lime carbonate, calcium citrate malate, Calcium of intensifiens, pearl powder etc. at present, although they may be that effectively their major parts can not directly be absorbed by human intestinal.
Commercially available Chemicals calcium acetate is by after wood distillation by product wood vinegar and the slaked lime effect, gets its filtrate evaporate to dryness, recrystallization and makes, and its purposes is system acetone and makes printing and dyeing mordant, stabilizer for plastics and chemical reagent.Because wood vinegar contains a certain amount of methyl alcohol poisonous and soluble in water, in the calcium acetate crystallisation process, methyl alcohol is also sneaked in the xln thereupon, therefore this calcium acetate anorexia with or do pharmaceutical.Data at home and abroad is not found that calcium acetate is edible at present as yet or is made pharmaceutical data by retrieval.
One of purpose of the present invention is the calcium acetate of developing the human consumption of a kind of energy or using as pharmaceutical product.
Two of purpose of the present invention provides a kind of production method of new calcium acetate.
Three of purpose of the present invention provides a kind of constant of 27 kinds of needed by human and calcium acetate of trace element of containing.
These and other objects of the present invention will embody further and launch by following specific descriptions.
The method of production calcium acetate of the present invention may further comprise the steps:
A, select ore also to clean up, become rubble below 3 centimetres with crusher in crushing then;
B, the ore after the fragmentation is put into reaction vessel, adding concentration is the acetum of 20-30wt%, measures to flooding ore slightly to get final product.
C, the reaction 8-24 hour, to bubble seldom, leaching liquid PH is 5-6, gives off leaching liquid;
D, filtration, the elimination coarse particles imports settling tank, adds unslaked lime or slaked lime under agitation gradually and leaves standstill after liquid PH is 9-12, and post precipitation is got supernatant liquor;
E, use the pressure filter press filtration, clear leaching liquid, import settling pond then and clarify out the water white transparency leaching liquid;
F, to add concentration in leaching liquid be that the acetic acid of 40-70wt% is transferred PH to 6-6.5;
G, use spray drying device become white powder calcium acetate product with liquid dried, and product granularity is＜200 orders.
In the present invention, described ore can be limestone or marble, can also be optical calcite or calcite, can be used alone, and also can use their mixture.In general must carry out geological mapping, sampling, chemical examination to the places of origin of raw materials, select color pure white, the pure ore of matter is made raw material, requires to contain CaCO
3＞95%, KgCO
3＜1.5%.Do not contain harmful element lead, cadmium, arsenic, mercury, and "dead", adopt near the ore in Heyuan city preferably, preferably adopt the domestic ore in Lianping County, Guangdong Province.
In the present invention, also comprise conventional post-processing step,, be packaged in plastics (bag) bucket product warehousing preservation etc. as the examination and test of products.
In the present invention, use Glacial acetic acid or acetin to be diluted with water to the acetum of concentration, the Glacial acetic acid or the acetin that adopt the zymamsis method to make preferably as 20-30wt%.
In the present invention, employed reaction vessel can be commercially available conventional containers, preferably garden post made from synthetic glass or plastics or flat column shape, and volume decide according to needing, and is changeable, and upper end open is also with cover, and raw material adds thus; The bottom is tapered, and switch is installed to discharge leaching liquid and insolubles particulate; Pressure filter and spray-dryer all can directly be buied from the market, and general drying plant factory is all on sale.
In the present invention, the ore of adorning is not can dissolve in the reaction vessel, but dissolves gradually and reduce.Therefore each soak and discharge leaching liquid after, should add ore to original height, and then add acetic acid and reacted, the rest may be inferred later on continuous production.
Product of the present invention is through Guangdong Province's food quality supervision test house, Guangzhou Institute of Analysis, and it is nontoxic to human body that proof detects in health institute of Zhongshan Medical Univ., has advantages such as easy absorption, utilization ratio height, instant effect.Except that calcic, also contain the constant and the trace element of 27 kinds of needed by human.More particularly, because this product is the ionic calcium salt, therefore dissolving fully can directly be absorbed by the human small intestine in the aqueous solution, and specific absorption is 76.3%, and stocking rate is 75.6%.
The prepared calcium acetate of method of the present invention can directly eat or make injection, tablet or electuary etc. for the people, to treat the human body diseases that causes owing to calcium deficiency.
The prepared product of method of the present invention is a white crystalline powder, and odorless, little sweetness and bitterness are very easily water-soluble, and do not contain VITAMIN 0, and it is neutral that potential of hydrogen is, to the stomach nonirritant, very remarkable to the calcium replenishing effect.
Below further specify the present invention by specific embodiment.
