    摘要: The invention relates to a method for producing an aliphatic polyester, utilizing starch as a raw material. The invention produces an aliphatic polyester by the steps of hydrolyzing starch to obtain glucose, oxidizing the glucose to obtain gluconolactone or gluconic acid, reducing the gluconolactone or the gluconic acid to obtain caproic acid, chlorinating the caproic acid to obtain 6-chlorocaproic acid, cyclizing the 6-chlorocaproic acid to obtain &egr;-caprolactone, and executing ring-opening polymerization of the &egr;-caprolactone.

    摘要: A polyhydroxyalkanoate containing in a molecule at least one unit represented by the chemical formula (1). The polyhydroxyalkanoate is a biodegradable plastic with enhanced melt-processability and exhibits excellent charging stability, high chargeability, and enhanced dispersibility when used as a charge control agent of a toner in an electrophotographic process. (R denotes -A1(—SO2R1)x. R1 is selected from OH, a halogen atom, ONa, OK, and OR1a. R1a and A1 are selected from a substituted or unsubstituted aliphatic hydrocarbon structure, a substituted or unsubstituted aromatic ring structure, and a substituted or unsubstituted heterocyclic structure. Further, m and x are integers selected from 1 to 8, and when two or more units exist, each of R, R1R1a, A1, m, and x is defined as above independently for each of the units.)

    摘要: A large amount of a medium containing a volatile chlorinated organic compound (VOC) with a low concentration is passed through an adsorber filled with an adsorbent which adsorb and desorb the VOC to collect the VOC in the medium in the adsorber; a gas containing water vapor is then brought into contact with the adsorbent to desorb and discharge the VOC from the adsorber; the desorbed gas is cooled to condense the VOC and water; a small amount of the VOC with a high concentration vaporized from the condensate is further irradiated with light in the presence of chlorine to decompose the VOC; and the decomposed product is subsequently treated. This constitution can allow a large amount of the VOC with a low concentration to be irradiated with light in the presence of chlorine to efficiently treat the VOC.
