2-methyl-1-butene

The solubilities of ZnCl,in 2-methyl-1-butanol and 3-methyl-1-butanol systems were measured with equilibrium method,respectively.

用平衡法分別測定了氯化鋅在2-甲基-l-丁醇和3-甲基-1-丁醇中的溶解度,用靜態法分別測定了在100℃～140℃不同溫度下含飽和ZnCl2的2-甲基-1-丁醇和3-甲基-1-丁醇的飽和蒸汽壓,進一步運用擬二元法原理分別用Glapeyron方程和Antoine方程關聯試驗數據。

Kinetic resolution of(R,S)-2-methyl-1-butanol was completed by porcine pancreatic lipase-catalyzed transesterification with triacetin in a solvent-free system.

1前言(S)-2-甲基-1-丁醇在手性精細化學品及藥物合成中有重要的作用[1]。

Adding a little bit TBA in the reaction material was found to reduce the surface acidity of sulfonic group cation resin catalyst,improve the catalyst s adsorption selectivity on 2-methyl-1-butene,and keep the conversion rate of crude isopentene in isomerization reaction at a high level,and markedly improve the selectivity of 2-methyl-2-butene.

通過在反應原料中加入少量的叔丁醇,降低了磺酸基陽離子交換樹脂催化劑表面的酸性,提高了催化劑對2-甲基-1-丁烯的吸附選擇性,使粗異戊烯在異構化反應中的轉化率保持較高水平,顯著提高了2-甲基-2-丁烯的選擇性,成功地開發了一種粗異戊烯異構化反應的新工藝。
