    • A curable substituted resorcinol-based epoxy resin was developed having structural formula (I), wherein at least one of R1, R2 or R3 is selected from the group consisting of (a) hydrogen, (b) halogen, (c) a saturated hydrocarbon having 1 to 10 carbon atoms, (d) an unsaturated hydrocarbon having 1 to about 10 carbon atoms, (e) an aralkyl group, and (f) a benzoyl group. The aralkyl group has structure (II), wherein at least one of R4, R5 or R6 is selected from the group consisting of (a) hydrogen, (b) an alkyl group having 1 to about 4 carbon atoms and (c) halogen. The benzoyl group has structure (III), wherein R7 is selected from the group consisting of hydrogen, halogen and an alkyl group having 1 to 4 carbon atoms. Another curable substituted resorcinol-based epoxy resin was developed having general structural formula (IV), wherein at least one of R8, R9, R10 or R11 is selected from the group consisting of hydrogen, halogens and alkyl groups having 1 to about 10 carbon atoms. To minimize potential toxicity, the above derivatized resorcinol epoxies were synthesized, along with a series of thermoplastic tougheners. The physical and mechanical properties of the neat resins and of the toughened resins are presented in this patent.

    • A process for making phenylene dioxydiacetic acid comprises (a) contacting a dihydroxybenzene under reaction conditions with a salt of haloacetic acid in a solution without adding a haloacetic acid to produce a salt of phenylene dioxydiacetic acid; and (b) optionally converting the salt of phenylene dioxydiacetic acid to free phenylene dioxydiacetic acid. In some embodiments, 1,3-phenylene dioxydiacetic acid (RDOA) is made by reacting resorcinol with sodium chloroacetic acid in a reaction mixture with a pH in the range of about 7 to about 11 and at a temperature from about 70 °C to 105 °C. By adjusting the reactions conditions, a relatively high yield of 1,3-phenylene dioxydiacetic acid (i.e., greater than 80%) is obtained. The purified acid can be used in the synthesis of polyester, such as polyethylene terephthalate.
    • 制备亚苯基二氧基二乙酸的方法包括(a)在反应条件下使二羟基苯与卤代乙酸盐在溶液中接触而不添加卤代乙酸以产生亚苯基二氧二肟酸的盐; 和(b)任选将亚苯基二氧代二乙酸的盐转化为游离的亚苯基二氧基二乙酸。 在一些实施方案中,1,3-亚苯基二氧二氢乙酸(RDOA)是通过使间苯二酚与氯乙酸钠在反应混合物中反应制备的,反应混合物的pH为约7至约11,温度为约70℃至105℃ C。 通过调整反应条件,可以获得相当高的1,3-亚苯基二氧二氢乙酸的收率(即大于80%)。 纯化的酸可用于合成聚酯,如聚对苯二甲酸乙二醇酯。
