PURPOSE: To contactually produce N,N,N-trisubstd. nitrogen-contg. compds. useful as solvents, liquid absorbers, polyurethane catalysts, acidic gas scrubbing agents, etc., from carboxylated N,N,N-trisubstd. nitrogen-contg. compds. n CONSTITUTION: The N,N,N-trisubstd. nitrogen-contg. compds. are obtd. by bringing the carboxylated N,N,N-trisubstd. nitrogen-contg. compds., more preferably the compds. of formulas I to II (R, R 1 , R 2 are the residues of org. compds., R may form a heterocyclic alkyl ring which may have a substituent by crosslinking with each other), for example, methyldiethanolamine carbamate, etc., into contact with multi component metal oxide catalysts contg. preferably group IIA metal oxide and group IIIA or group IIIB metal oxide, more preferably magnesium oxide and aluminum oxide and having a surface area preferably larger than about 50 m 2 /gm under conditions effective for forming the N,N,N- trisubstd. nitrogen-contg. compds. n COPYRIGHT: (C)1992,JPO |
