The gas phase oxidation of propylene to acrylic acid at high temperature (generally 300 deg.-400 deg.C, and especially 320 deg-350 deg.C), is carried out in the presence of water vapour and a catalyst system containing oxygen, molybdenum, tungsten, tellurium and at least one from iron, ...

Define acrylic acid. acrylic acid synonyms, acrylic acid pronunciation, acrylic acid translation, English dictionary definition of acrylic acid. n. An easily polymerized, colorless, corrosive liquid, C3H4O2, used as a monomer for acrylate resins. America
The invention relates to an improved method for producing acrolein and/or acrylic acid from propylene, characterised in that a basic compound is added to the reaction gas containing propylene. Said method enables the formation of unwanted propanaldehyde and/or propionic acid by-products to be signif...
Acrylic acid is produced from propene which is a by product of ethylene and gasoline production. CH2=CHCH3 + 1.5 O2→ CH2=CHCO2H + H2O Because acrylic acid and its esters have long been valued commercially, many other methods have been developed but most have been abandoned for economic or...

(Danner et al., 1998). Currently, most acrylic acid is obtained from the catalytic partial oxidation of propene which is a by-product of ethylene and gasoline production. In this two-step oxidation reaction via acrolein is usually preferred, achieving about 90 % overall yield (Lin, 2001;...
They may be homopolymers of acrylic acid, crosslinked with an allyl ether pentaerythritol, allyl ether of sucrose or allyl ether of propylene. In a water solution at neutral pH, PAA is an anionic polymer, i.e. many of the side chains of PAA will lose their protons and acquire a negative...
