industrial manufacture of propylene carbonate
editAccording to Shaikh and Sivaram's 1996 review of organic carbonates in 1996 (volume 96, page 951-976), the majority of carbonates are prepared by the phosgenation of hydroxy compounds. I'm aware that the startup company Novomer aims to make propylene carbonate from propylene oxide and CO2 (http://www.novomer.com/our-technology), but as far as I know, the phosgenation route is still the predominant way this compound is manufactured. — Preceding unsigned comment added by Turricanfan (talk • contribs) 17:21, 28 October 2014 (UTC)
- Well I read through Ullmann's Encyclopedia and they also indicate that most carbonates are made from phosgene ("The phosgenation of hydroxy compounds is currently
the most important method for producing carbonic esters"). Ethylene and propylene carbonates are the exceptions, probably because the strain-induced reactivity. Compared to diphenyl- and dimethylcarbonate, the cyclic are made on a modest scale.--Smokefoot (talk) 02:08, 30 October 2014 (UTC)
solubilliy of carbon dioxide in propylene carbonate
editPropylene carbonate can be used to preferentially absorb CO2 from synthesis gas or other gas mixtures at a working pressure of 250 psig, for example. The CO2 can be removed from the propylene carbonate using a steam jet. I operated a pilot plant using this technology.
