Use editor

It is widely used in the synthesis of medicine, pesticide, perfume and so on. [2] bisphenol products can be made by reacting with phenols; aliphatic imines can be made by reacting with monoamines; under the action of alkaline catalyst, the reaction is rapid, and this property can be used as dehydrating agent; because there is water in carbamate and epoxy coating, which affects the curing, this product can be added for dehydration at this time; and because the reaction between this product and water is endothermic reaction, it can be used as the removal of heat sensitive substances. Water agent.
