TL;DR: In this article, a process for preparing an optically active trans-3-substituted glycidic acid ester compound of the formula (I) is described.
Abstract: A process for preparing an optically active trans-3-substituted glycidic acid ester compound of the formula (I): ##STR1## wherein ring A is a substituted or unsubstituted benzene ring, and R1 is an ester residue, which comprises: preparing a solution of one optical isomer (A) and the other optical isomer (B) of the ester compound (I), both of which are the optical isomers due to the asymmetric carbons at 2- and 3-positions, and an ester compound (B') which is different from the isomer (B) only in the ester residue R1, crystallizing the optical isomer (A) from the solution up to the extent that the optical isomer (A) is crystallized without the precipitation of the optical isomer (B) due to the presence of the ester compound (B') though the optical isomer (B) would precipitate if the ester compound (B') were not present, and isolating the crystals of the optical isomer (A), whereby a desired optical isomer (A) can be obtained in high purity and in a high yield such that the desired isomer can be crystallized until the concentration of the desired isomer in the mother liquor becomes very low as compared with conventional processes.

TL;DR: In this paper, a triphasic bioreactor for physico-chemically treating a gas is described, which consists of a reaction chamber with a liquid and biocatalysts in suspension in the liquid for catalyzing a reaction between the gas and the liquid to obtain a treated gas and a solution containing a reaction product.
Abstract: A triphasic bioreactor for physico-chemically treating a gas is disclosed. The triphasic bioreactor comprises a reaction chamber with a liquid and biocatalysts in suspension in the liquid, for catalyzing a reaction between the gas and the liquid to obtain a treated gas and a solution containing a reaction product. A gas bubbling means is provided in the reaction chamber for bubbling the gas to be treated into the liquid thereby dissolving the gas into the liquid and increasing a pressure inside the reaction chamber. The bioreactor further comprises a liquid inlet in fluid communication with the reaction chamber for receiving the liquid and filling the reaction chamber, a liquid outlet in fluid communication with the reaction chamber for releasing the solution and a gas outlet in fluid communication with the reaction chamber to release the treated gas. The bioreactor further comprises a retention device to retain the biocatalysts in the reaction chamber. The invention also concerns a process using the triphasic bioreactor. The triphasic bioreactor may advantageously be used for removing carbonic dioxide from a CO 2 -containing gas.

TL;DR: In this paper, a simple extraction of racemic p-methoxyphenyl glycidic acid methyl ester ((+/-)-MPGM) is used for enzymatic resolution, belonging to the field of application of enzyme engineering.
Abstract: The invention relates to simple extraction of racemic p-methoxyphenyl glycidic acid methyl ester ((+/-)-MPGM) which is used for enzymatic resolution, belonging to the field of application of enzyme engineering. After synthesis of (+/-)-MPGM, toluene is added to dissolve (+/-)-MPGM, and the by-product NaCl and redundant sodium methoxide do not enter into a toluene phase; filtration is carried out so as to obtain the toluene phase containing (+/-)-MPGM; and water and Serratia lipase are added for resolution and preparation of (-)-MPGM. In the whole process, loss of (+/-)-MPGM can be effectively reduced.
