(5,5'-바이아이소벤조퓨란)-1,1'-테트론 C화학적 특성, 용도, 생산

화학적 성질

BPDA (3,3',4,4'-Biphenyltetracarboxylic dianhydride) is a raw material for the polyimide resin component of one of the super-engineering plastics. It is used for many important information and electronic technology products such as mobile phones and copying machines.

용도

3,3',4,4'-biphenyltetracarboxylic dianhydride be used for the preparation of a polyimide material.

제조 방법

The preparation of 3,3',4,4'-Biphenyltetracarboxylic dianhydride is as follows:In a nitrogen atmosphere, add N-(3-N,N-dimethylamino-propyl)-4-chlorophthalimide (26.65g, 0.1moL),Zinc powder (3.25g, 0.05moL), anhydrous NiCl2 (127.5mg, 1mmoL),Triphenylphosphine (250mg, 1mmoL) and 70 mL of anhydrous DMAc were stirred at 50°C for 24 hours, and 55mL of solvent DMAc was recovered under reduced pressure. Add 80g of xylene to the system and reflux (recrystallize), filter out the inorganic matter, the clarified filtrate will be cooled and precipitated, filtered, and vacuum dried for 10 hours. 21.8g of 3,3',4,4'-biphenylbisimine was obtained with a yield of 94%. In a 100mL reaction flask, add 4.62g (0.01mol) of the above 3,3',4,4'-biphenylbisimine and 9g of 20% sodium hydroxide aqueous solution, and heat to reflux for 24 hours. Filter and adjust pH=1 with concentrated hydrochloric acid to obtain 3,3’,4,4’-biphenyltetracarboxylic acid. After filtering, wash with water three times and reflux with water with 20mL trimethylbenzene.2.85g of white 3,3′,4,4′-biphenyltetracarboxylic dianhydride was obtained, the yield was 97%.

일반 설명

3,3′,4,4′-Biphenyltetracarboxylic dianhydride (s-BPDA) is a rigid symmetric polyamide with a diamine having a long distance between amine groups and reactive endgaps.

Advantages

1.Excellent thermal stability
2.Good chemical resistance
3.Stable mechanical properties
4.Polyimide does not require the addition of flame retardants to prevent combustion.
