Abstract: A process for producing alkyl trifluoroacetates The present invention relates to a process for producing alkyl trifluoroacetates by reacting trifluoroacetic acid with an alkyl alcohol R—OH in an aqueous solution, and wherein the alkyl trifluoroacetate is separated from the reaction medium by means of direct rectification. In one aspect the present invention relates to a process for recovering trifluoroacetic acid in the form of alkyl trifluoroacetates from aqueous waste-water streams of preceding chemical transformations.

Abstract: The invention pertains to processes to produce dry biomass of pyripyropene producer organisms, processes to obtain pyripyropenes from such dry biomass, as well as to processes to produce compounds of Formula III and/or Formula IV and/or Formula V from the pyripyropenes obtained from the dry biomass. The invention does further pertain to the dry biomass itself, as well as processes using said dry biomass to obtain pyripyropenes for the production of compounds of Formula III and/or Formula IV and/or Formula V, including processes using said dry biomass to obtain pyripyropenes or compounds of Formula III and/or Formula IV and/or Formula V in order to produce pest control compositions, in particular insecticides, comprising such compounds.
