摘要： The invention relates to a method for producing trioxane by the trimerization of formaldehyde in an aqueous acidic solution and by subsequently separating out trioxane from a mixture (trioxane raw product) essentially consisting of trioxane, water and formaldehyde. The invention is characterized in that: a) the trioxane raw product from the trimerization is distilled; b) the trioxane is crystallized out; c) is separated out from the mother liquor; d) is subsequently melted, and; e) additional byproducts are removed by distillation.

摘要： O.Z. 0050/42919 In a process for producing filler-containing thermoplastic molding compositions by mixing fillers with thermoplastics in the melt, a) the fillers are mixed in a mixing apparatus in the melt with a low molecular weight thermoplastic having a melt viscosity of at most 30 Pas (measured at 20.degree.C above the melting point of the thermoplastic compound and at a shear gradient of 1,000 s-1), b) the product thus obtained is removed from the mixing apparatus, cooled and comminuted, and c) the comminuted product is then subjected in the solid phase to a post-condensation.

摘要： Linear high molecular weight polyamides containing a regulated level of amino and carboxyl end groups are prepared in a continuous process by reacting polyamides in the melt with polyamide-forming diamines or dicarboxylic acids by continuous mixing for a residence time of ~ 10 minutes, granulating the polyamide, and further condensing the polyamide granules thus obtained in solid phase in the presence of inert gases until the viscosity has reached the desired level.

摘要： A process for continuous extraction of polyamide particles in an essentially vertical extraction column using an aqueous extractant comprises using an extraction column that is divided into two zones and performing an extraction with a recirculating 15-40% strength by weight aqueous epsi-caprolactam solution in the first zone and then with countercurrent water at a from 5 to 40° C. lower temperature in the second zone. The process provides for economical extraction of polyamides with a low level of monomers and oligomers.

摘要： FIELD: polymer production. SUBSTANCE: polyamides are prepared from mixture of at least one lactam and water under polyamide- forming conditions. In the first step, mixture containing 0.5 to 7 wt % water is heated to 220-310 C at pressure allowing reaction mixture to be single-phase and liquid to achieve degree of polymerization at least 85%, after which pressure is adiabatically thrown off and polymerization further proceeds at 215 to 300 C. For example, first-step polycaproamide with molecular weight 3000 to 9000 (on the base of end group content) and polycaproamide with molecular weight 3000 to 14000 are described. High-molecular polycaproamide is prepared by solid-phase polycondensation of low-molecular one upon heating. EFFECT: enhanced process efficiency. 12 cl, 4 tbl, 5 ex
