    Abstract: CYCLIC FORMAL IS MANUFACTURED BY CYCLIC REACTION OF AN ALKYLENE GLYCOL AND AN ALDEHYDE IN A REACTOR, PRODUCING FORMAL MIXED WITH UNREACTED ALDEHYDE AS AN IMPURITY, WHICH IS REDUCED IN AMOUNT BY CONNECTING THE REACTOR TO A DISTILLATION TOWER AND CONTINUOUSLY SUPPLYING A RAW ALKYLENE GLYCOL TO THE DISTILLATION TOWER FROM WHICH UNREACTED FORMALDEHYDE AND A CYCLIC FORMAL ARE BEING DISTILLED, AND CONTINUOUSLY REACTING THEM WITH SUPPLIED RAW FORMALDEHYDE BY COUNTERCURRENT FLOW DURING DISTILLATION. WATER CONTENT IS AZEOTROPIC ADMIXTURE WITH CYCLIC FORMAL CAN BE REMOVED BY AZEOTROPIC DISTILLATION WITH A HYDROCARBON AZEOTROPIC ADMIXTURE WITH WATER, DISTILLING WATER FROM THE CYCLIC FORMAL.

    Abstract: A process for producing an oxymethylene copolymer comprises the steps of polymerizing trioxane and cyclic ether in the presence of a boron trifluoride catalyst, adding a hindered amine compound to the polymer obtained by said polymerization, and stabilizing unstable chain ends of the polymer. The oxymethylene copolymer thus obtained provides excellent heat resistance and superior mechanical properties.

    Abstract: An elastic polyester is continuously produced by continuously feeding an aromatic polyester and a lactone to an extruder (6), which is provided with a cylinder having an aspect ratio (L/D) ranging from 3 to 50 (wherein L represents the cylinder length of a reactor and D the inner diameter of the cylinder) and at least one screw and wherein the space in the cylinder provided with the screw accounts for 70 % or less of the internal volume of the cylinder, and reacting the lactone with the aromatic polyester while conducting the melting, carrying and kneading of the feed material in the extruder (6). Since the screw can be turned with a high speed, the effect of kneading can be enhanced and the reaction time can be shortened. Since the obtained elastic polyester is excellent in durability represented by thermal and weathering resistances, rubber elasticity, and mechanical properties, it has a wide range of uses such as automotive parts, electric and electronics components and machine parts.

    Abstract: Cyclic formal is manufactured by cyclic reaction of an alkylene glycol and an aldehyde in a reactor, producing formal mixed with unreacted aldehyde as an impurity, which is reduced in amount by connecting the reactor to a distillation tower and continuously supplying a raw alkylene glycol to the distillation tower from which unreacted formaldehyde and a cyclic formal are being distilled, and continuously reacting them with supplied raw formaldehyde by countercurrent flow during distillation. Water content in azeotropic admixture with cyclic formal can be removed by azeotropic distillation with a hydrocarbon azeotropic admixture with water, distilling water from the cyclic formal.
