DIISOOCTYLPHOSPHINIC ACID Use and Manufacturing
To synthesize bis(2, 4, 4-trimethylpentyl)phosphinic acid, a 1.5 liter autoclave was charged with 40 g (0.377 moles) of sodium hypophosphite; 40 g of acetic acid; 132.3 g (0.943 moles) of diisobutylene (80percent); and 2.8 g (0.019 moles) of tert-butyl peroxide initiator. The mixture was then heated to about 135° C. during an 8 hour day for about four days, i.e., a total of 30 hours and 1.4 g of the initiator was added at the beginning of each day. The reaction mixture was monitored by
Bis(2,4,4-trimethylpentyl)phosphonic acid is a colorless to pale yellow liquid with a fruity aroma; it is an extractant that can be used for nickel-cobalt separation and rare earth separation.
Phosphinic acid, P,P-bis(2,4,4-trimethylpentyl)-: ACTIVE|PMN - indicates a commenced PMN (Pre-Manufacture Notices) substance.
