1,1,3-TRIMETHOXYPROPANE synthesis

13synthesis methods
1,1,3-TriMethoxypropane can be used as organic synthesis intermediate and pharmaceutical intermediate, mainly in laboratory research and development process. It was synthesized from Methanol mixed with glycerol (4  :1 ) reacted under ZrO2/SO42- super acid catalyst for 4.3 minutes at 200° C(0.1 psia (5 mm Hg)). 
-

Yield: 21.8%

Reaction Conditions:

ZrO2/SO42- super acid catalyst at 20 - 200; under 5 Torr; for 0.0716667 h;Product distribution / selectivity;

Steps:

2
Methanol was mixed with glycerol at a ratio of 4 to 1 by weight at ambient temperature. The mixture was pumped to a reactor packed with ZrO2/SO42- super acid catalyst synthesized as above. The reactor temperature was maintained at 200° C. and the reactor pressure was maintained at 0.1 psia (5 mm Hg). The reaction time (residence time based on the reactor volume/liquid feed rate) was 4.3 minutes. The glycerol in the feed was almost completely consumed, and the methanol consumed was 28.9 wt. % of the input. The products and other details are shown in Table 2 below:
