    Abstract: PROBLEM TO BE SOLVED: To provide a method for producing an aliphatic polyester-based polymer, by which the high mol.wt. aliphatic polyester-based polymer having a practically sufficient melting temperature, an excellent color tone, and an excellent mechanical strength can profitably be produced at a practically high polymerization rate. SOLUTION: This method for producing an aliphatic polyester based polymer comprises polycondensing (i) a mixture of an aliphatic dicarboxylic acid or its diester with an aliphatic diol or (ii) the preliminary condensation product of the mixture as a reaction raw material in the presence of a transesterification catalyst. Therein, at least one protonic acid selected from an organic phosphonic acid of the formula: O=P(OH)2R (R is an aliphatic group or an aromatic group), aliphatic and/or aromatic compounds having sulfonic groups or sulfate ester groups and sulfuric acid is used as an auxiliary catalyst for the catalyst.

    Abstract: PROBLEM TO BE SOLVED: To obtain a polyester excellent in mechanical strength and fabricability and having a novel structure by subjecting an aliphatic dicarboxylate, an aliphat ic glycol and monoacylated glycerin to condensation reaction. SOLUTION: The polyester is obtained by subjecting an aliphatic dicarboxylic acid represented by formula III (wherein R1 is an 1-12C divalent aliphatic group; R4 and R5 are each an 1-4C alkyl group; and t is 0 or 1), an aliphatic glycol represented by formula IV (wherein R2 is a 2-12C divalent aliphatic group) and a monoacylated glycerin represented by formula V (wherein R3 is a 6-22C aliphatic group) to condensation reaction. The amount of the component of formula V is 0.001-0.10 mol per 1 mol of the sum of the components of formulas III and IV. By the condensation reaction is obtained a biodegradable aliphatic polyester having a number average molecular weight of 10,000-1,000,000 comprising an ester portion A represented by formula I (wherein p is a molar ratio of the ester portion of the polyester) and an ester portion B represented by formula II (wherein (r) is a molar ratio of the ester portion of the polyester), the molar ratio (r) of the ester portion B being in the range of 0.001-0.10.

    Abstract: PURPOSE:To efficiently transport and store org. sludge by fluidizing a caked org. sludge at a specified temp. and the pressure above the saturated steam pressure at that temp., transporting and storing the fluidized material. CONSTITUTION:A concd. org. sludge is introduced into a dehydrator 1, and the dehydrated sludge is introduced into a fluidizer 2 which is a heat-exchange reactor. A heating medium is introduced from a line 15, and the org. sludge is preheated in the fluidizer. The preheated sludge is supplied to a line 16 in the fluidizer and heated to the reaction temp. by the heating medium discharged from a line 21. In this case, the reaction temp. is controlled to >=150 deg.C, and the reaction pressure is adjusted above the saturated steam pressure at the reaction temp. The fluidized material is introduced into a cooler 3 and cooled by the heating medium from a line 20, and the heating medium is passed through the line 15 to heat the fluidizer 2. The fluidized material is then transferred to the treating equipment by a feed pump 6 or transported to the remote sludge treating equipment.
