Abstract: The invention relates to a method for producing a phosphor-nitrogen condensate, comprising the following steps: i) production of a precondensate by reacting urea with melamine at a temperature of at least 170 DEG C, ii) reaction of the precondensate obtained in step i) with phosphoric acid at a temperature of at least 180 DEG C and use of the condensate as a flameproofing agent in plastics.

Abstract: Isolation of trimethoxysilane from a TMS/methanol mixture comprises forming and separating a TMS-rich extract phase and a methanol-rich raffinate phase by adding a methanol-soluble (in)organic salt. Isolation of trimethoxysilane (TMS) from a TMS/methanol mixture comprises forming and separating a TMS-rich extract phase and a methanol-rich raffinate phase by adding a methanol-soluble (in)organic salt and optionally nonpolar organic solvents, the amount of salt being such that the wt. ratio of TMS to methanol in the extract phase is at least 94 to 6 wt.%.
