Abstract
The invention relates to a cocoyl dimethyl ammonium iodine oxide complex, and provides a chemical intermediate for preparing an iodophor disinfectant. The cocoyl dimethyl ammonium iodine oxide complex comprises the following components the following components in part by weight: 80 to 90 parts of cocoyl dimethyl ammonium oxide, 10 to 15 parts of iodine (I) and 2 to 5 parts of citric acid. A synthetic process comprises the following steps of: adding 80 to 90 kilograms of cocoyl dimethyl ammonium oxide into a closed stainless steel reaction kettle with temperature control, heating to the temperature of between 50+/-2 DEGC, and adding 2 to 5 kilograms of citric acid; heating to the temperature of between 95+/-2 DEGC, and adding 10 to 15 kilograms of iodine; and reacting in the reaction kettle for 3 hours, allowing a reactant to perform system circulation for 1 hour, and cooling to the temperature of between 30+/-2 DEGC for discharging. The cocoyl dimethyl ammonium iodine oxide complex is in the appearance of dark violet thick liquid, and has the pH value of between 5 and 6 and iodine content of over 10 percent.
Description
【Technical field】 [0001] The present invention relates to a kind of intermediate raw material of making iodophor disinfectant, and the present invention relates to the manufacture method of cocoyl dimethyl ammonium oxide iodine complex. 【Background technique】 [0002] Disinfectants, the concept given by the National Disinfection Standards, are chemical factors that can kill infectious or harmful microorganisms in the external environment. At present, disinfectants are widely used, not only in the medical field, but also in people's daily life. Disinfectants are currently mainly used in the medical field. There are many types of disinfectants, which can be divided into sterilants, high-efficiency disinfectants, medium-efficiency disinfectants and low-efficiency disinfectants according to their disinfection capabilities. According to the direction of use, they can be divided into environmental and object surface disinfectants, skin and mucous membrane disinfectants, Air disi...
