Title: Semi-continuous production of optically active alcohol
Inventor: NEGISHI SATOSHI
IPC: C12P41/00
Filed: 1994-11-29
Abstract: PURPOSE: To enable semi-continuous production of an optically active alcohol which is useful as a starting substance for medicines and agrochemials by non- solvent reaction of a racemic alcohol and a fatty acid ester in the presence of an enzyme, separation of the unreactive optically active product and continuation of the reaction of the residue. CONSTITUTION: In the presence of a heat-resistant lipase, a racemic alcohol and a 16 or more C fatty acid ester of 1,3-propane diol which may be substituted with an alkyl group in its 2-carbon are subjected to anhydrous ester- interchanging reaction in no solvent at a temperature over 81 deg.C under normal pressure. Then, unreacting R isomer or S isomer-rich optically active alcohol is distilled under reduced pressure to separate from the residue. The residue is maintained under reduced pressure to effect anhydrous transesterification reaction in the presence of a heat-resistant lipase in no solvent over 81 deg.C, while an optically alcohol rich in R- or S-isomer liberating from the reaction is distilled under reduced pressure. Further, racemic alcohol is added to the residue to repeat this process to obtain this optically active alcohol semi-continuously.

Filed: 1990-11-22
Abstract: PURPOSE:To simply and stably rotate a centrifuge by constituting the taper angle of a taper shaft of two stages of the angle same as that of the taper hole of a rotor and an angle different from that of said taper hole. CONSTITUTION:A rotor 1 in which a sample 2 to be separated is inserted is rotated at a fast speed by a drive device 6. The drive torque at this time is transmitted by the friction at the contact part of the taper hole 3 provided to the rotor 1 and the taper shaft 4 provided to the upper end of the drive device 6. Now, when the rotor 1 is arranged on the taper shaft 4 and rotation is stated, the rotor 1 and the taper shaft 4 are brought to a contact state along a taper 2 (12) having a wide diameter and, therefore, stability at the time of arrangement and that at the starting time of the rotation of the rotor 1 are hardly different from conventional ones. When the rotor 1 is rotated at a high speed, the rotor 1 comes into contact with the taper hole 3 at the contact part (1) 13 being the boundary of a taper (1) 11 and the taper (2) 12 and the rotor 1 becomes hard to incline and torque can be transmitted without generating unstable vibration.
