    • 1,3-Pentadiene is polymerized in an inert gaseous atmosphere from a mixture of saturated and unsaturated hydrocarbon molecules. At least 50 percent by weight of said molecules have 5 carbon atoms. An anionic polymerization initiator in conjunction with an organic polar solvent is used to effect polymerization. Cyclopentadiene, active hydrogen compounds and other polymerization-terminating compounds may be inactivated and separated from the mixture of hydrocarbon compounds before starting polymerization. As an alternative, inactivation and separation of cyclopentadiene, active hydrogen compounds and polymerization-terminating compounds may be omitted provided the anionic polymerization initiator is employed in an amount to (a) inactivate such compounds and (b) initiate polymerization of 1,3-pentadiene.The polymer of 1,3-pentadiene so prepared is then hydrogenated or functionalized by further reaction.
    • 1,3-丁二烯在惰性气体气氛中由饱和和不饱和烃分子的混合物聚合。 所述分子的至少50重量%具有5个碳原子。 使用与有机极性溶剂结合的阴离子聚合引发剂进行聚合。 在开始聚合之前,可以将环戊二烯,活性氢化合物和其它聚合终止化合物失活并与烃化合物的混合物分离。 作为替代方案,可以省略环戊二烯,活性氢化合物和聚合终止化合物的灭活和分离,只要阴离子聚合引发剂的用量为(a)灭活这些化合物和(b)引发1,3-戊二烯的聚合 。 然后将如此制备的1,3-戊二烯的聚合物通过进一步的反应氢化或官能化。

    • An aqueous formulation for cleaning grease and oil from metal, plastic, glass or other surfaces includes water, a surfactant, and a corrosion-inhibiting amount of a 2-piperazinone. The surfactant is chosen from the class of materials possessing at least some ability in aqueous solution to disperse the grease and oil in an aqueous suspension. The formulation preferably includes both an anionic and a nonionic surfactant. The 2-piperazinone inhibits corrosion of the metal or other surface without unduly reducing the dispersive ability of the surfactant(s). The preferred 2-piperazinones for use in the disclosed invention are 4-(2-hydroxyethyl)-2-piperazinone (4-HEP) and N,N-dimethyl-2-piperazinone (NNDP). The formulation is used by agitation in contact with the surface to be cleaned, for example, by mechanical agitation of the surface, by spraying the formulation against the surface, or by the application of ultrasound waves. A concentrate for preparing the formulation contains the surfactant(s) and 2-piperazinone at a concentration 5 to 20 times their concentrations in the formulation; the concentrate is then diluted with 5 to 20 parts of water to yield the formulation.
    • 用于从金属,塑料,玻璃或其他表面清洁油脂和油的水性制剂包括水,表面活性剂和防腐蚀量的2-哌嗪酮。 表面活性剂选自在水溶液中具有至少一些能力的材料,以将油脂和油分散在水性悬浮液中。 制剂优选包括阴离子和非离子表面活性剂。 2-哌嗪酮抑制金属或其他表面的腐蚀,而不会过度降低表面活性剂的分散能力。 用于本发明的优选的2-哌嗪酮是4-(2-羟乙基)-2-哌嗪酮(4-HEP)和N,N-二甲基-2-哌嗪酮(NNDP)。 通过与待清洁的表面接触的搅拌使用该制剂,例如通过机械搅动表面,通过将制剂喷雾在表面上,或通过施加超声波来使用。 用于制备制剂的浓缩物含有浓度为制剂浓度5至20倍的表面活性剂和2-哌嗪酮; 然后将浓缩物用5至20份水稀释以得到制剂。

    • A method for a liquid-liquid extraction of hydrophilic organic compounds from aqueous solutions thereof is described. The method generally includes intermixing a sufficient quantity of a specified glycol ether with the aqueous liquor at a first temperature to form a suspension comprising an aqueous raffinate phase and a glycol ether extract phase; separating the glycol ether extract phase from the aqueous raffinate phase; heating the glycol ether extract phase to a second, higher temperature to form a suspension comprising an aqueous extract phase containing a portion of the hydrophilic organic compound and a glycol ether raffinate phase; and separating this glycol ether raffinate phase from the aqueous extract phase. The selected glycol ether has an inverse solubility in water and the partition ratio, value K, for the hydrophilic organic compound is greater than 0.1. This method is useful for recovering valuable hydrophilic organic acids produced via fermentation or produced or used in various manufacturing processes.
