Abstract

The invention discloses a medical intermediate desulfurizing agent and a preparation method thereof. The medical intermediate desulfurizing agent comprises the components in parts by weight: 100-200 parts of an active component, 200-300 parts of a carrier and 1000-2000 parts of deionized water, wherein the active component is a composition of potassium carbonate, potassium hydroxide, sodium hydroxide, methylamine and ethylamine, and the carrier is a composition of coconut shell activated carbon, activated aluminum oxide and a ZSM-5 molecular sieve; a processing flow of the coconut shell activated carbon comprises the steps: screening raw materials, and selecting coconut shells with qualified conditions, preferably Indonesia coconut shells; and carbonizing: putting the screened coconut shells into carbonizing equipment, sintering at a high temperature to a certain degree, sealing a charcoal kiln to enable air to enter, continuously heating by using waste heat, carrying out dry distillation to enable moisture and wood tar in the coconut shells to be distilled out, and thus forming coconut shell charcoal. The medical intermediate desulfurizing agent is excellent in desulfurizing effect, the materials are easy to obtain, and the preparation method is simple to operate.

Description

technical field [0001] The invention belongs to the technical field of desulfurizing agents, and in particular relates to a pharmaceutical intermediate desulfurizing agent and a preparation method thereof. Background technique [0002] There are many kinds of pharmaceutical intermediates, and the dosage of each product is low, which makes it impossible to form large-scale production. At present, most of the pharmaceutical intermediate production enterprises in my country are private enterprises with flexible operation and small investment scale, basically ranging from several million to 10 to 20 million yuan. The geographical distribution of enterprises is relatively concentrated, mainly in Taizhou, Zhejiang and The area centered on Jintan, Jiangsu. The update speed of pharmaceutical intermediate products is fast, and the profit rate of a product will drop sharply after 3-5 years after it is generally launched on the market. This forces companies to continuously develop new ...
