Cellulose diacetate (also known as cellulose acetate or cellulose acetate) is a synthetic derivative of cellulose. The following is an introduction to its nature, purpose, production method, and safety information.
Nature:
1. Appearance: Cellulose diacetate is a colorless or slightly yellow solid.
2. Solubility: It is soluble in organic solvents such as acetic acid, but insoluble in water.
3. Physical properties: Cellulose diacetate has good strength and heat resistance.
Description of Cellulose diacetate :
According to the degree of substitution(DS), Cellulose acetate can be commonly classified to cellulose diacetate(DAC) and cellulose triacetate(TAC). Usually, DAC has DS with 2.2-2.5 while TAC has DS with above 2.7.(DS is an average number, It represents the number of -OH which is substituted by -C0CH3
