Cyrene a biobased alternative to NMP, DMF and similar solvents


Summary

Cyrene is a bioderived dipolar aprotic solvent and a safe alternative to petrochemical derived solvents such as NMP, DMF and DMAC


Description

Cyrene is currently being produced at a 50 tonne scale plant and has Reach Annex VII approval.  Annex VIII is expected by H2 2018.

Cyrene has been shown to be effective in a range of applications including graffiti removal, as a solvent for synthesis, for dispersion and for dissolving polymers such as polyethersulphone

Cyrene is not a drop in replacement and performance needs to be evaluated on a case by case basis.  Circa is happy to provide samples for evaluation


Practical implementation

Cyrene is being used as an alternative to petrochemical based dipolar aprotic solvents by a customer in the electronic chemicals industry where bioderived, safety and performance are all valued In a like for like study, Cyrene has been shown to disperse ten times more graphene than NMP


Possible replacement to

NMP, N-methylpyrrolidone, N-methyl-2-pyrrolidone, (CAS 872-50-4) DMF, N.N-dimethylformamide (CAS 68-12-2) DMAC, Dimethylacetamide (CAS 127-19-5)
