9 Claims

1. 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 m³to 150 m³;

means for mixing the composition of step (a); and

means for controlling the temperature of the composition of step (a).
