Propylene has been catalytically oxidized by dioxygen to acrylic acid and/or its esters in high yield (60–80%) in acidified aqueous and/or alcoholic solutions of palladium–561 giant clusters, whereas ethylene has been converted to acetic acid; this is the first example of acid–promoted ...

Define propylene oxide. propylene oxide synonyms, propylene oxide pronunciation, propylene oxide translation, English dictionary definition of propylene oxide. n. a colorless liquid epoxide, C3H6O, similar to ethylene oxide: used mainly for making propyl
Heterogenous catalytic partial gas phase oxidation of propylene to acrylic acid comprises introducing a reaction gas initial mixture (I) containing propylene and molecular oxygen and an inert dilution gas in a first reaction stage at increased temperature into a first reaction zone; reducing the tempera...
Summary: In this paper, the graft of poly(propylene) fiber with acrylic acid is investigated. The effects of grafting temperature, monomer concentration, and grafting time on the grafting degree of acrylic acid onto poly(propylene) fiber are discussed. In contrast to the conventional method of de...
PROBLEM TO BE SOLVED: To provide a catalyst which, when producing acrylic acid from propane and/or acrolein, is excellent in catalytic performance such as catalytic activity and selectivity and in catalyst life, and which exhibits stable... I Norihiko,井口 徳彦,N Toshiya,... 被引量: 0发表...
temperature by means of inert gases, the loaded inert gases are passed to the countercurrent absorption for the recovery of the acrylic acid contained therein, and the acrylic acid is distilled off under reduced pressure from the carboxylic ester solution which is free from acetic acid and water....
