Latest Patents

One of her latest patents is titled "Pressure ethoxylation in dense gases to produce hydroxyalkyl ester monomer." This patent discloses a pressure process for preparing a hydroxyalkyl ester monomer and oligomer that can be utilized to create polyesters such as polyethylene terephthalate (PET). The process involves reacting dicarboxylic acid and alkylene oxide in a compressed gas medium, achieving a specific mixture of monohydroxyalkyl ester and bishydroxyalkyl ester. The reaction is conducted at a pressure that ensures the density of the gas medium is at least half the critical density, with a mole ratio of alkylene oxide to dicarboxylic acid of less than about 2:1.

Another significant patent is "Pressure polymerization of polyester." This process allows for the preparation of a polyester polymer or copolymer under superatmospheric pressure conditions. The reaction occurs in a tubular reactor under turbannular flow conditions, with a mole ratio of glycol equivalents to carboxylic acid equivalents maintained between 1.0:1 and 1.2:1. The process operates at elevated temperatures and pressures, resulting in a polymer product with a degree of polymerization greater than 40.
