4,4′-(1-Methylethylidene)bis[benzenamine] Use and Manufacturing
In a 1 L autoclave, Aniline hydrochloride 500 g, water 199 g, After 80 g of acetone was added, Under stirring, The mixture was heated to 160 ° C. and reacted for 18 hours.After cooling down, The solution was transferred to a 3 L separating funnel, diluted with 1600 g of ethyl acetate and 200 g of water. Next, 356 g of a 48 wtpercent sodium hydroxide aqueous solution was added and alkali treatment was carried out, The organic layer obtained by liquid separation was washed with 745 g of water.As a result of quantitating this organic layer by gas chromatography analysis using normal-hexadecane as an internal standard, 249 g of 2, 2-bis (4-aminophenyl) propane was produced (yield 80percent - based on acetone charged moles).In a 1 L autoclave, Aniline hydrochloride 500 g, water 199 g, After 80 g of acetone was added, Under stirring, The mixture was heated to 160 C. and reacted for 18 hours.After cooling down, The solution was transferred to a 3 L separating funnel, diluted with 1600 g of ethyl acetate and 200 g of water.
