THE propylene oxidation to acrolein and oxidation of propylene to acrylic acid two-step process with acrolein AS INTERMEDIATE IMPROVES WITH THE USE OF GASES DILUYENTES Anhydrous TO REDUCE OR REPLACE THE STEAM FLOWS IN REACTION. IN PARTICULAR THE USE OF DILUYENTES Anhydrous SOAR THERMAL CAPACITY FLOW IN GAS MIXTURE THINNER AT LEAST about 6.5 calories / MOLECULAGRAMO (C) improves the selectivity towards the desired products AND REDUCE THE BURDEN OF WATER SYSTEM.
