Talk:Glycerolysis

RfC: Article Desperately In Need Of Qualified Editors
The spelling in this article is horrible, so bad that I don't even know what the author was trying to say. I'll leave the re-write to an experienced chemist. Is there really such a thing as "phallic acid"? Stonemason89 (talk) 19:36, 16 July 2009 (UTC)
 * I fixed the spelling error (phthalic acid is real). But I agree, the "Mono glycerolysis..." chunk of the article is a mess. The English spelling and grammar is poor but could be fixed, but the whole tone feels wrong (WP is not a how-to manual) even if we spent time deciphering the meaning. Could just nuke it IMO.

 * I agree on both counts. It's nigh indecipherable and mostly a procedure. I've taken it out and left it here if anyone wants to salvage anything from it. Strad (talk) 17:49, 26 July 2009 (UTC)

Removed section
Mono glycerolysis is an important step in making of alkyds. Generally, base catalysts such as Litharge is used (Eg - Linseed oil is mixed with penta erythrotol ~15 % by wt & heated under nitrogen to 250 *C, with 0.05 % of Litharge as catalyst). The end point is checked by the solubility of the mass in Methanol. Generally if the mass is soluble by 1: 3 it is OK. Now the heating is stopped / cooled to ~100 / other acid like Phthalic anhydride atc are added. This is a general alkyd preparation process. We can make a variety of trans esters (eg veg oil+ ethylene glycol) or ethoxy ethanol (cellosolve) or a number of glycols/ polyols to make a variety of esters that can be used in Leather/ Textile preparations. By making a Propylene glycol Trans ester& Washing this product with water to a neutral- the product can be used as a food deformer/ in the manufacturing of reducing the viscosity of sugar solution/ also in brevry industry wher foam is a problem. The molar ratio of veg oil to the polyol will decide the solubility and its properties.
