摘要： A process for making bis(aryloxyalkyl)terephthalates useful as antiplasticizers for thermoplastic polyesters is disclosed. Dimethyl terephthalate is reacted with an excess of an aryloxyalkanol in the presence of a condensation catalyst to produce an intermediate mixture comprising a bis(aryloxyalkyl)terephthalate, a mono(aryloxyalkyl)terephthalate, and unreacted aryloxyalkanol. This mixture continues to react at reduced pressure while unreacted aryloxyalkanol is removed and the mono-ester content is reduced to less than 1 mole % based on the combined amounts of mono- and bis-esters. Both steps are performed substantially in the absence of oxygen. Additional unreacted aryloxyalkanol is then removed to provide a purified bis(aryloxyalkyl)terephthalate having an overall purity of at least 98 mole % and a yellowness index less than 10. Careful control over catalysis, exposure to air, and other process conditions enables the preparation of high yields of bis(aryloxyalkyl)terephthalates that have low color and other valuable attributes. A method of producing bis(aryloxyalkyl)terephthalate articles having improved compressive strength is also disclosed.

摘要： Hydroxamic acids are efficiently isolated from aqueous reaction media in which they are produced as solids by adding to the reaction mixture with agitation, a coalescing amount of a water insoluble organic liquid, such as a light hydrocarbon or halohydrocarbon, which is a non-solvent for the hydroxamic acids. The coalesced particles float to the surface of the medium leaving behind a clear, aqueous phase which can be drained from the reaction vessel to leave the discrete particles of hydroxamic acid. Buoyancy of the particles is assisted by adding hydrogen peroxide to the reaction mixture or by bubbling air therethrough, usually after the coalescence.

摘要： Disclosed are automatic dryer added fabric conditioning articles and methods utilizing fabric conditioning compositions comprising from about 20 percent to about 80 percent by weight of a mixture of quaternary ammonium compounds, and between about 80 percent to about 20 percent by weight of a mixture of glycerin and glyceryl esters, wherein the fabric conditioning compositions possess a melting point of about 30° C. to about 65° C. The conditioning compositions of the present invention are preferably employed in combination with a dispensing means adapted for use in an automatic clothes dryer. The fabric conditioning compositions may be coated onto substrates, and the fabric conditioning articles thereby obtained used to impart softness and anti-static properties to fabric. The method portion of the invention involves the commingling of damp fabrics with the fabric conditioning compositions in an automatic clothes dryer to impart softness and anti-static properties to the fabric. The compositions of this invention, when coated onto substrates are mechanically and thermally stable and thus are not dislodged or prematurely released when substrate is flexed, twisted and/or stored at room temperature.
