Bentonite functioned by potassium compounds as a solid catalyst for biodiesel production [PDF]
Heterogeneous catalysts, especially those produced with functionalized clays, can be used for methyl transesterification at moderate temperatures. The use of bentonite clay functionalized by potassium compounds (KF, KOH, K2CO3, KCl and K2SO4) in the ...

Chiral cyclopropenimine–thiourea organocatalysts enabled both high reactivity and precise stereocontrol in the ring‐opening polymerization of rac‐lactide. The bifunctional system exhibited a TOF up to 1,710 h−1 with Pm = 0.90 at 25°C, and achieved Pm = 0.99 at −78°C while maintaining a TOF of 16.3 h−1.
