In this work, studies of the transesterification using sodium hydroxide as a catalyst of mixtures of soybean oil/coconut oil (SO/CNO) and soybean oil/castor oil (SO/CO) before and after ...

The pH was then adjusted to 6.8 using sodium hydroxide. The absorbance was registered, at 560 nm before (Ao) and after (Am) adding 5 µL of the sample to be analyzed, so as to obtain a Sb III ...

Sequential desilylation with tetrabutylammonium fluoride (TBAF) and ester hydrolysis of 9 using sodium hydroxide furnished the 2-hydroxy-16-nor- ent -pimar-8 (14)-en-15-oic acid (HPA, 1) in excellent ...
