[0019] The present invention is further described below.
[0020] Inositol nicotinate production process of the present invention, carry out according to the following steps:
[0021] 1. Chlorination reaction: Add 100kg of pyridine with a water content of no more than 0.5% into a dry 1000L enamel reaction tank, then add 107kg of phosphorus oxychloride, stir well, and gradually add 150kg of nicotinic acid under cooling conditions. Heat up to 65-75°C, keep warm for 0.8-1.2 hours;
[0022] 2. Esterification reaction: Add inositol slowly under cooling conditions, heat up to 80-90°C after adding inositol, and react for about 1 hour;
[0023] 3. Filtration and washing water: stir the reactant with drinking water, and then carry out filtration after cooling. The resulting filtrate is washed with hot purified water until the liquid has no bitter taste of pyridine, and the filter cake is dried to obtain inositol nicotinate Crude;
[0024] 4. Decolorization and refining: dissolve the...
