Patent Number Title Of Patent Date Issued
7799942 Production of terephthalic acid di-esters September 21, 2010
Disclosed is a process for the preparation of a terephthalic acid di-ester by the esterification of terephthalic acid with an alcohol at elevated and normal temperature and pressure while the water of the reaction is removed from the reaction mixture via an inert gas or a column.
7741509 Conversion of terephthalic acid to Di-n-butyl terephthalate June 22, 2010
Disclosed is a process for the preparation of di-n-butyl terephthalate by the esterification of terephthalic acid with n-butanol in the presence of a strong acid while employing a fractionating column.
7674931 Method for producing 2,2,4-trimethyl-1,3-pentanediol di-2-ethylhexanoate March 9, 2010
A method for maximizing the yield of 2,2,4-trimethyl-1,3-pentanediol di-2-ethylhexanoate (TMPD di-2-ethylhexanoate) from the reaction of 2,2,4-trimethyl-1,3-pentanediol (TMPD Glycol) and 2-ethylhexanoic acid through the intermediate compound 2,2,4-Trimethyl-1,3-pentanediol-2-ethylhex
7361779 Low-melting mixtures of di-n-butyl and diisobutyl terephthalate April 22, 2008
Mixtures of terephthalate diesters having lowered freezing points and methods of making the terephthalic acid diesters. The method includes contacting a first alcohol, a second different alcohol and dimethyl terephthalate in the presence of a catalyst to thereby form the terephthalat
7276621 Production of di-(2-ethylhexyl) terephthalate October 2, 2007
Disclosed is a process for the preparation of di-(2-ethylhexyl) terephthalate by the esterification of terephthalic acid with 2-ethylhexanol at elevated temperature and pressure while the water of reaction is removed from the reaction mixture.
6657075 Continuous process for tertiary butyl esters December 2, 2003
Disclosed is a continuous process for the production of tertiary butyl esters by the reaction of a ketene and tertiary butyl alcohol containing a finite concentration of water. The process may be carried out in an absorber reactor with continuous recovery and purification of products by
