Properties of commercial immobilized lipases and values for the conversion1 of formic acid to phenethyl formate.
| Immobilized Lipase | Specificity/Selectivity | Immobilization Support | Conversion 1 |
|---|---|---|---|
| Novozym 435 | Nonspecific | Acrylic resin (Lewatit vp oc 1600) |
47.83% |
| Lipozyme RM IM | 1,3-specific | Phenol–formaldehyde copolymer (Duolite ES 562) |
0.28% |
| Lipozyme TL IM | 1,3-specific | Silica gel | 0.34% |
| Lipase PS Amano IM | Stereoselective acylation | Diatomaceous earth | 0.60% |
1 The conversion yield (%) was calculated by gas chromatograph (GC) analysis.
