Example 1: General procedure for the synthesis of bis(2,4,4-trimethylpentyl)hypophosphite: 40 g (0.377 mol) of sodium hypophosphite, 40 g of acetic acid, 132.3 g (0.943 mol) of diisobutene (80% purity), and 2.8 g (0.019 mol) of tert-butyl peroxide initiator were sequentially added to a 1.5-liter pressure vessel. The reaction mixture was heated and reacted at 135 °C for 30 hours, during which time 1.4 g of initiator was replenished every 8 hours. The reaction process was monitored by 31P NMR and the reaction mixture contained 75.3% of bis(2,4,4-trimethylpentyl)phosphinic acid product and 12.1% of monoalkyl phosphinic acid by-product. Upon completion of the reaction, 220 g of the reaction mixture was transferred to a conical flask and heated at 70-80°C to reduce viscosity. Thirty-eight grams of water was slowly added until separation of the two phases occurred, and the aqueous phase (pH ≈ 5) was separated and removed. The organic phase was washed with 75 g of 4% sodium hydroxide solution to remove the resulting 89.2 g aqueous layer. Subsequently, the organic phase was acidified and washed with 50 g of 10% sulfuric acid solution to remove the aqueous phase. The acidified and washed organic phase was filtered through PS filter paper and the volatile components were removed by vacuum distillation. The final product was 95 g of bis(2,4,4-trimethylpentyl)hypophosphonic acid with 93.7% purity and 86.9% yield based on phosphorus NMR calculations. The composition of the product is detailed in Table I.
