Title: Optical resolution of racemate by optically active polymer
Inventor: YUUKI HIRAAKI
IPC: C07B31/00
Filed: 1980-02-19
Abstract: PURPOSE:To carry out the optical resolution of a mixture of a wide variety of racemates including compounds free of polar group, in high efficiency, by the chromatography using an adsorbent comprising an optically active polymer obtained by  the polymerization of triphenylmethyl methacrylate. CONSTITUTION:An optically active polymer having a polymerization degree of >=20, pref. >=100, and an absolute specific rotatory power [alpha]D<20> of >=50 deg. and composed mainly of the constitution unit of formula, is prepared by the ionic polymerization of triphenylmethyl methacrylate in the presence of an optically active anionic catalyst, e.g. Li(R)-N-(1-phenylethyl)anilide, in a solvent pref. at -78- +40 deg.C. The polymer is used as an adsorbent of chromatography for the optical resolution of racemic mixture. The molecule of the polymer takes a tight spiral structure having optically active asymmetric structure by the molecular asymmetry. Accordingly, the whole surface of the adsorbent is asymmetric, and the efficiency of optical resolution is improved.

Filed: 1986-01-31
Abstract: PURPOSE:To permit members such as concrete and the like in an elastic cylindrical body to be forcibly fed securely and smoothly and simplify a pressure feed device, by rotating cam shafts by a single drive motor and successively pressing the cylindrical body by a pair of passing members. CONSTITUTION:A pair of pressing members 11 are actuated by a rotating force transmitted through cams 7 from cam shafts 6a, 6b driven by a drive motor in order to press an elastic cylindrical body 20 successively so that concrete and the like in the elastic body 20 can be forcibly fed towards an outlet 22 of the elastic body 20 successively. With such an arrangement, members to be fed such as concrete which has relatively inferior mobility can be forcibly fed securely and smoothly. In addition, a force to forcibly feed large members can be obtained by a drive motor with a relatively small output, which makes the construction of the pressure feed device simple, small and compact.

Abstract: PURPOSE: To obtain the sintered body of high purity and high density by heating raw material powder to sublimate and remove the impurities adsorbed on the raw material powder surfaces then hermetically sealing the same in a vessel, putting the vessel in a hot hydrostatic press and pressing the same under elevated temperature.  
     CONSTITUTION: Raw material powder, e.g., CdS powder is heated to about 500°C under vacuum to sublimate not less than 20% of the total weight of the raw material powder and remove the impurities such as moisture contained in the raw material powder. Thence, the residues in the vessel are put in a vessel of glass, ceramics or metals, after which the vessel is put in a hot hydrostatic press and is pressed under elevated temperature, whereby the CdS sintered body of high purity is obtained. If the sublimated vapors are recovered, the losses by the reduced weight of the powder raw material itself are prevented. Rather, the powder recovered from the foregoing vapors is of fine particles, has no deposite and is ideally suited as raw material powder.
