use | used for iodine value determination, organic synthesis, and can be used as a strong oxidant to determine the iodine value of oils and fats. Organic synthesis. |
Production method | 1. Pass chlorine gas into the secondary sublimation iodine to obtain the variant iodine monochloride. The amount of chlorine gas introduced should be completely iodine reaction, and the end point of the reaction is that the solid is completely converted into liquid. The obtained liquid is distilled and 100-101.5 oC fraction is collected, which is the finished product. 2. Put 220g of secondary sublimation iodine in the weighed flask. Pass chlorine into the flask until the weight gain reaches 62.5g. Output 282g. The product is an alpha variant. It should be carried out under good ventilation conditions. |
