  • Publication number: 20250002440
    Abstract: Processes are provided for the conversion of diglycol terephthalates to a dialkyl terephthalate, specifically bis(hydroxyalkyl) terephthalate to dimethyl terephthalate at low temperatures. The process involves initial catalyzed transesterification of bis(hydroxyalkyl) terephthalate with methanol at a first temperature of between 0° C. and 70° C. for an initial time followed by a second stage of the reaction at or below 30° C. In particular, the process is tolerant of significant amounts of glycol and water, so the precursor bis(hydroxyalkyl) terephthalate does not necessarily need to be highly pure or dry. Filtration of the reaction mixture allows recovery of high yields of dimethyl terephthalate of sufficiently high purity such that further purification is often not required in order to be repurposed for the manufacture of polyesters.

  • Patent number: 10961180
    Abstract: The invention provides branched trialkylamine oxides with improved properties. The trialkylamine oxides of the invention produced from branched trialkylamines, in one embodiment, can be made using certain branched C10-12 enals and aldehydes. The invention also provides an trialkylamine oxide having the formula: wherein R5, R6 and R7 are independently at least one of C3H7, C2H5, CH3, or H, or mixtures thereof; and wherein R5 and R6 are not H at the same time. In one embodiment, the trialkylamine oxides of the invention can be useful in making various products, for example, as surfactants.

  • Publication number: 20210009926
    Abstract: The invention provides a process for the preparation of a modified triethanolamine/fatty acid ester composition ratio by treatment of a conventional tnethanolamine fatty acid ester composition with a hydrolytic enzyme. Also provided are novel mixtures of tnethanolamine and mono-, di-, and tri-esters of fatty acids which are useful in the preparation of cationic surfactants useful in fabric softening applications. In one aspect, the method increases the triester fraction without significantly affecting the amount of mono-ester and unesterified species, which in turn adds to the flexibility in the formulation of the corresponding fabric softening compositions.
