摘要： Disclosed herein is an exhaust gas control device for internal combustion engines. The exhaust gas control device has a main exhaust pipe (3) communicating with an exhaust manifold (2) used for guiding exhaust gas discharged from a combustion chamber (1) of an engine, a catalytic converter (6) arranged on a predetermined position of the main exhaust pipe (3) for purifying unburnt fuel discharged with the exhaust has and having a plurality of sequentially arranged catalyst units (6a, 6b, 6c), and an unburnt fuel collection tank (8) provided with a plurality of cooling fins (9) and connected to the catalytic converter (6) through a branch pipe (7). The collection tank (8) collects purified unburnt fuel after the unburnt fuel is treated by the catalytic converter (6) so as to remove noxious materials therefrom.

摘要： Disclosed is a process for the regioselective preparation of glycerol derivative in a high efficiency and yield. The process for the regioselective preparation of 1-R1-2-R2-3-acetyl-glycerol derivative comprises the steps of: obtaining 1-R1-3-protecting group-glycerol by introducing a protecting group to 3-position of 1-R1-glycerol; obtaining 1-R1-2-R2-3-protecting group-glycerol by introducing R2 group into 2-position of 1-R1-3-protecting group-glycerol; and carrying out the deprotection reaction and the acetylation reaction of 1-R1-2-R2-3-protecting group-glycerol at the same time. Wherein, R1 and R2 are fatty acid groups having 16 to 22 carbon atoms, and are different from each other; and the protecting group is trityl group or trialkylsilyl group.
