9,10-Dihydro-9-oxa-10-phosphaphenanthrene 10-oxide Use and Manufacturing
10 g of 6-chloro-6H-dibenz[c, e][1, 2]oxaphosphorin (0.0426 moles), 1.2 g hydrochloric acid (0.0335 moles) and 2.1 g of water were introduced into a reacting chamber and stirred for 5 minutes to form a solution. 1. Synthesis of DOPO; Add one mole of CDOP with a 500 milliliter toluene into a reactor. Add one mole of water (about 18 g) by dropping for about one hour. The condenser uses water for cooling. The hydrochloric acid vapor is lead to the neutralization sink by going through the ventilated tube which connects to the top of the condenser. When the dropping is finished, reflux it for an hour. Then introduce the nitrogen into the solution, reflux it for another 2 hours for blowing out the remaining hydrochloric acid vapor. After return to room temperature, white solid DOPO precipitates. The yield is about 95percent after filtering and dying.HPPA and 1g of p-toluenesulfonic acid was added to 150mL of toluene, heated to reflux with water, kept 4 hours after steaming 100mL of toluene.After cooling the remaining solution precipitated a large amount of white solid, filtered and dried to give 31.6g of DOPO with a total yield of 97.5percent and a purity of 96.1percent.
