1,3,2-dioxathiolane 2,2-dioxide - Reference Information
| LogP | -0.45 at 23℃ and pH1.4-1.7 |
| surface tension | 66.8mN/m at 1g/L and 20 ℃ |
| Use | As an additive for the electrolyte of a lithium ion battery, the additive has the function of suppressing the decrease of the initial capacity of the battery, increasing the initial discharge capacity, reducing the expansion of the battery after being placed at a high temperature, and improving the charging and discharging performance and the number of cycles of the battery. Hydroxyethylating reagents for organic synthesis synthesize drug intermediates. It can also be used as a raw material for synthesizing certain heterocyclic compounds for gelatin hardening, antihypertensive drugs and new double surfactants |
