1) tribromopentaerythrito
三溴季戊四醇
2) tripentaerythritol
三季戊四醇
1.
When n (NaOH) / n (MeCHO) =1 and n (MgO) / n (MeCHO) =0 1, the reaction gave pentaerythritol, dipentaerythritol and tripentaerythritol with the yields of 36 0%, 41 5% and 12 5% respectively, while only with n (NaOH) / n (MeCHO) =1 1 in the absence of MgO, their yields were 39 8%, 41 8% and 11 6% respectively.
结果表明 ,与液体碱NaOH的碱催化作用相比 ,固体碱MgO上的产物季戊四醇、双季戊四醇和三季戊四醇在收率方面水平相当 。
