HYDROQUINONE DIPHTHALIC ANHYDRIDE - Introduction
Hydroquinone Diphathalic Anhydride (HQDP)(Hydroquinone Diphathalic Anhydride, HQDP for short) is an organic compound with the chemical formula C20H10O6. The following is a description of the nature, use, preparation and safety information of HQDP:
Nature:
- HQDP is pale yellow to white crystalline with a strong pungent odor.
-It is poorly soluble in water, but soluble in most organic solvents such as alcohols, ethers and ketones.
- HQDP will decompose at high temperatures and release toxic gases.
Use:
- HQDP is mainly used as a raw material for polyimide resins and is widely used in electronics, medical, aerospace, automotive and other industries.
-It has excellent high temperature resistance, corrosion resistance and electrical insulation properties, and can be used in the manufacture of electronic components, sensors, insulating coatings, etc.
Preparation Method:
-The preparation of HQDP can be carried out by the condensation reaction of hydroquinone (hydroquinone) and phthalic anhydride (phthalic anhydride).
-The specific preparation method can be adjusted and optimized according to different needs to achieve the required purity and yield.
Safety Information:
- HQDP is an irritating chemical that may cause irritation and inflammation in contact with the skin and eyes.
-Avoid inhaling its powder or vapor when using HQDP, and ensure that it is operated in a well-ventilated environment.
-After exposure to HQDP, immediately flush the affected area with plenty of water and seek medical advice.
-To avoid the risk of fire and explosion, keep away from open flames and high temperatures.
