The invention relates to a process comprising: reacting isobutyraldehyde with an aqueous solution of urea in the presence of a phase transfer catalyst to form isobutylidene diurea. Preferably, the phase transfer catalyst is a quaternary ammonium salt, more preferably benzyltriethylammonium chloride. Even more preferably, the process is performed in one pot.
本发明涉及一种工艺,包括:在相转移催化剂的存在下,将
异丁醛与
尿素水溶液反应,形成异丁基亚甲基二
脲。优选地,相转移催化剂是季
铵盐,更优选的是苄基三乙基
铵氯化物。更加优选的是,在一个反应釜中进行该工艺。
