Abstract
The present invention relates to a process for preparing ammonium (meth-) acrylate, aqueous ammonium (meth-) acrylate solutions obtainable by such process, and (meth-) acrylic acid homopolymers or copolymers obtainable by polymerizing such ammonium (meth-) acrylate. The invention furthermore relates to a modular, relocatable bioconversion unit for manufacturing aqueous ammonium (meth-) acrylate solutions.
Claims9
A process for producing ammonium (meth-) acrylate, said process comprising the following steps:
- (a) adding the following components (i) to (iii) to a reactor to obtain a composition for bioconversion:
- (i) a biocatalyst capable of converting (meth-) acrylonitrile to ammonium (meth-) acrylate;
- (ii) (meth-) acrylonitrile;
- (iii) aqueous medium;
- and
- (b) performing a bioconversion on the composition obtained in step (a) in a reactor;
- wherein the reactor is a relocatable bioconversion unit, the unit comprising:
- a single walled reaction vessel, the vessel having;
- a volume from 10 m3 to 150 m3;
- means for mixing the composition of step (a);
- and
- means for controlling the temperature of the composition of step (a).
