on total amine feed sup b weight percent of ethylenediamine and ethanolamine consumed in the reaction sup c weight percent of noncyclic polyethylene amine products formed the results in tables 5 and 6 clearly show that sulfur containing catalysts including sulfuric acid are effective for producing linear polyethylamine polyamines from the reaction of ethylene diamine and ethanolamine boron sulfate gave extremely high selectivity at a low level e g 0 62 mole percent ethylenediamine surprisingly with the sulfate catalyst higher concentration of catalyst resulted in substantially reduced selectivity with only modest improvements in conversion see boron sulfate boron phosphate on the other hand experienced a doubling in conversion while selectivity dropped in half a series of runs similar to examples 15 22 were made except that a mole ratio of diamine to alkanolamine of 1 1 was used in the presence of sulfur containing catalysts tables 7 and 8 show results in terms of the amount of polyamines produced by the reaction conversion and selectivity are specified table 7__________________________________________________________________________polyethylene amines from ethylenediamine and ethanolamine sup a level mole temp ae ae ae run catalyst u00b0 c pip teda deta aep taea teta baep peeda teta tepa baep peeda__________________________________________________________________________24 boron 1 25 300 64 75 14 33 5 32 0 61 2 32 sulfate25 boron 2 50 300 7 14 0 08 2 38 10 17 0 19 4 00 5 89 3 88 1 46 4 53 0 26 sulfate26 ammo 0 60 300 4 43 16 75 1 63 0 93 3 38 2 43 0 67 0.
