Abstract

1 / 1 resumo “ pro ce sso ” ㉠descrito um processo para produzir poliois (tais como neopentil glicol) que compreende reagir formaldeã­do e um outro aldeã­do na presenã§a de um catalisador de trialquilamina e um promotor de base para formar um produto da reaã§ã£o de condensaã§ã£o aldã³lica. o promotor de base melhora a remoã§ã£o de sais contendo nitrogãªnio antes da hidrogenaã§ã£o do hidroxi aldeã­do para produzir o poliol. o processo melhorado tambã©m reduz a utilizaã§ã£o de catalisador de trialquilamina, melhora a recuperaã§ã£o do catalisador de trialquilamina, e reduz os sais contendo nitrogãªnio antes da hidrogenaã§ã£o.
