2,2′-Ethylenedianiline Use and Manufacturing

A. Preparation of Supported Nickel Catalyst Take 4.75g of nickel chloride hexahydrate in a 25ml round bottom flask, dissolved in 15ml of deionized water, Add 20g of neutral alumina, stir with ultrasound and dry overnight. Weigh 0.3g sodium borohydride, Configured to 800ml 0.01mol / L solution, 5g precursor was added to a 1L flask, added with mechanical stirring, Sodium borohydride aqueous solution, the product was filtered and dried to obtain the desired catalyst.B. Preparation of 2, 2-diamino bibenzylTake a capacity of 10ml round bottom flask, add 300mg o-nitrobenzyl chloride, 300mg catalyst, 2ml deionized water, 2ml of 60percent hydrazine hydrate was slowly added dropwise under magnetic stirring until completely added and stirred at room temperature for 20 minutes, The product is obtained. After the product was extracted with ethyl acetate, it was found by GCMS that about 51percent of the target product was obtained. The catalyst was washed with water and ethanol three times and then dried for use.
