Abstract
The invention provides a prodn. method of raw medicine, particularly a link of medical oyster calcium carbonate solution. the oyster calcium carbonate solution is prepared by dry reaction of active calcium and carbon dioxide directly or wet reaction of active calcium and ammonium acid carbonate in double layers closed container.
Description
Technical Field
The invention relates to a production method of a raw material medicine, in particular to a production method of pharmaceutical-grade oyster calcium carbonate, belonging to the technical field of pharmaceutical raw material medicines.
Background
Pharmaceutical grade oyster calcium carbonate is a drug substance prescribed by the national drug administration and the national pharmacopoeia committee to replace activated calcium because: the active calcium is pollution-free Concha Ostreae, and is prepared by calcining at high temperature and hydrolyzing to obtain raw material medicine containing Ca (OH)2The calcium content is 46-53%, the pH value is greater than 11, and the calcium-containing water-based fertilizer is strong alkaline and has irritation to intestines and stomach. The new national drug standard WS-10001- (HD-1034) -2002 of the pharmaceutical-grade oyster calcium carbonate is specified as follows: the oyster calcium carbonate is prepared from pollution-free oyster shell by high temperature calcining and converting to obtain calcium carbonate (CaCO)3) The calcium content should be 39.4-40.4%. After the new standards have been implemented, the focus of product development has been on how to prepare pharmaceutical grade oyster calcium carbonate from activated calcium, and more research has been focused on how to reduce the calcium content and alkalinity (PH) of activated calcium. The inventor finds that at present, the following conditions are mainly existed: adding citric acid and malic acid into the active calcium; calcining activated calcium or Concha Ostreae at high temperature, and directly neutralizing with organic acid (acetic acid, citric acid, malic acid, gluconic acid, etc.) water solution; dry ice (the method has uneven calcium content distribution and moist products) is added into the active calcium package. The method can not produce the pharmaceutical-grade oyster calcium carbonate which completely meets the national drug standard. It is also known to introduce carbon dioxide gas into the aqueous solution of activated calciumBody (CO)2) The method for conversion has the problems of long production process, high labor intensity, serious waste, high cost and the like. Furthermore, the direct incorporation of organic acid calcium with low calcium content into activated calcium does not ensure that the main component of the product is CaCO3。
Disclosure of Invention
The present inventors have conducted intensive studies in view of the above problems. The invention aims to provide a production method of pharmaceutical-grade oyster calcium carbonate, which has simple production process and easy quality control and completely meets the national drug standard. The method is characterized by comprising the following two methods:
(1) taking 1 mol weight of active calcium meeting the standard of the original medicine, puttinginto a double-layer sealed stainless steel container (which can be a rotary vacuum drier or a mixer) with a sandwich layer, directly charging food-grade or medical-grade carbon dioxide (CO) gas from the top through a pressure gauge and a pressure reducing valve2) Carbon dioxide gas (CO)2) The dosage of the calcium carbonate is 1-1.5 molar mass, the temperature of the interlayer is controlled to be 35-90 ℃ by cold water or hot water, and the calcium carbonate can be fully reacted for 3-24 hours to obtain the pharmaceutical-grade oyster calcium carbonate meeting the national drug standard. The chemical reaction equation is as follows:
(2) taking 1 mol mass of food-grade ammonium bicarbonate, putting the food-grade ammonium bicarbonate into a double-layer closed reaction kettle with an interlayer, adding 2-5 times of water for dissolving, adding 0.75-1 mol mass of active calcium meeting the original drug standard, controlling the temperature to be 35-90 ℃, fully reacting for 3-24 hours, stirring, cooling cold water to 25 ℃, filtering, precipitating, washing and drying to obtain the pharmaceutical-grade oyster calcium carbonate meeting the national drug standard. The chemical reaction equation is as follows: and ammonia can be recovered to prepare ammonia water. The invention has the advantages that: the production process is simple and easy to control, and the prepared product has high purity, low cost and no pollution.
Detailed description of the invention
Example 1: 74kg of active calcium meeting the standard of the original medicine is put into a double-layer sealed rotary vacuum drier with a sandwich layer, and 54kg of food-grade carbon dioxide (CO) gas is directly filled from the top through a pressuregauge and a pressure reducing valve2) The temperature in the interlayer is controlled to be 65 ℃ by cold water or hot water, the oyster calcium carbonate is obtained by fully reacting for 10 hours, the calcium content is 40.05 percent by detection, and other indexes meet the standard requirements. Example 2: adding 150kg of water into a double-layer closed reaction kettle with an interlayer, adding 79kg of food-grade ammonium bicarbonate, stirring and dissolving, adding 60kg of active calcium meeting the original medicine standard, controlling the temperature to be 90 ℃, fully reacting for 5 hours, stirring, cooling with cold water to 25 ℃, filtering, precipitating, washing with water, and drying to obtain 74.1kg of oyster calcium carbonate, wherein the calcium content is 39.7% by detection, and other indexes meet the standard requirements.
