| titleOfInvention | Process for producing phthalic esters |
| abstract | The invention provides a process for producing estersnphthalic acid by esterification of phthalic anhydridenaliphatic C 1 -C 6 alcohols in the presence ofna Tidg catalyst, optionallyncarborafine and kieselguhr. Just the essencenis that it is used for esterificationnin an amount of 0.001 to 0.5, preferably 0.05nup to 0.2% by weight, based on totalnesterification feed, mixed catalystnbased on activated TiOO.HgO gelnpromoted by the addition of 0.1 to 50% nmot_nof aluminum sulphate octadecahydrate, \ tnbased on TiO2 dry matter. Power consumptionnthe heat of the esterificationnthe process is interrupted when the acid number dropsnto a range of 3.0 to 0.1 mgnKOH / g esterification mixture followed by vacuum "ndistillation and steam strippingnremoves excess esterificationnThe component, the ester, is dewatered under vacuum and filterednthe mixed catalyst and the additive are separatednwell-used auxiliaries. DuringnIt is advantageous to use an addition for pinningnNaOH up to 0.5 wtnthe total amount of ester, preferablynas a 40% aqueous solution. |
