5-Sulfoisophthalic acid monosodium salt CAS 6362-79-4 (commonly known as trimonomer), mainly used to synthesize the third monomer of cationic dyeable polyester (CDP), so that CDP polyester fiber has good affinity for cationic fuel The chemical properties of the CDP fiber can be dyed under normal pressure. After dyeing, the color is bright, the color spectrum is complete, the color fastness is high, it is not easy to fade, and it has good antistatic, moisture absorption, anti-pilling and breathability, and is comfortable to wear.
Eugenol CAS 97-53-0 liquid. The boiling point is 254 °C (lit.), the relative density is 1.067 g/mL at 25 °C,and the flash point is >230 °F.
3-Fluorobenzaldehyde CAS 456-48-4 is a colorless or light yellow liquid with a pungent odor, which can be dissolved in many organic solvents such as ethanol, ether, dichloromethane, toluene, etc. It is easily oxidized to m-fluorobenzoic acid by oxygen in the air, therefore, it should be stored in a closed state.
