In this paper,the Friedel-Crafts reaction of phenol's alkylfiction,in which boric acid has used as catalyst and isopropyl alcohol as aikylfying reagent, has been researched,some factor of the reaction such as the proportion of the reactions and the reactional temperature have been disscussed.关...
3. Reimer-Tiemann reaction On treating phenol with chloroform in the presence of sodium hydroxide, a CHO group is introduced at ortho position of benzene ring. This reaction is known as Reimer - Tiemann reaction. The intermediate substituted benzal chloride is hydroly...

Process and apparatus for concentrating nitric acid A paint vehicle is obtained by heating a glycidyl ether of a polyhydric phenol having at least one -OH group and from 1-2 epoxy groups per mol. with a fatty oil having an iodine number of 70-220 at 75 F. until a clear solution is ob...
Selective O-Alkylation of Phenol with Methanol over Sulfates Supported on γ-Al2O3 - ScienceDirect The reaction of phenol with methanol was studied in a fixed-bed reactor system as a potential source for the production of methyl aryl ethers. For this rea... Samolada M.C.,E Grigoriadou,Z...
Organic synthesis remains a major challenge in drug discovery. Although a plethora of machine learning models have been proposed as solutions in the literature, they suffer from being opaque black-boxes. It is neither clear if the models are making corre
