| 摘要 |
The present invention provides a process for the production of an N,N-dialkylaminophenyl alkanol having the formula: in which R1 and R2, independently, are C1-C4alkyl, R3 is hydrogen, halogen, cyano, C1-C4alkyl or C1-C4alkoxy and n is an integer from 1 to 4, comprising reacting an aminophenyl alkanol having the formula: in which R3 and n have their previous significance, with at least two moles of a dialkylsulfate having the formula: in which R1 and R2 have their previous significance. N,N-dialkylaminophenyl alkanols so obtained are valuable as intermediates for a wide range of end-products and are also useful, e.g., as accelerators for the peroxide-catalyzed polymerization of vinyl monomers, especially in polymerizable or curable formulations employed in dental applications.
