摘要： A continuous process for the production of dichlorohydrin by the reaction of allyl chloride, water and chlorine having substantially lower energy requirements than conventional processes, wherein the reaction mixture is subjected to reverse osmosis to concentrate the dichlorohydrin and to provide a permeate stream substantially free of dichlorohydrin, which permeate stream is recycled to the reaction.

摘要： A method and apparatus is presented for determining surface tension of a liquid or interfacial tension between two dissimilar liquids by using a rigidly suspended probe with small sample sizes and by measuring probe force using a top-loading balance used for supporting the container of liquids under test. When a small sample size in a small container is used, capillary action between a probe and the container walls enhances the measured force, and an adjustment factor for the capillary action must be applied. A probe rigidly suspended to overcome capillary action between the probe and walls permits such measurements. For any sized sample, in accordance with Isaac Newton's third law of equal and opposite forces acting between objects, the force required for lifting a probe vertically from a liquid is equivalent to the reduction in weight of the liquid and container. Force magnitude is thus determined using a top-loading balance for observing weight change, either in the liquid while a suitably configured probe is withdrawn from the liquid or in a probe suspended by a direction converter resting on a top-loading balance while the container and liquid are lowered.
摘要翻译： 提出了一种方法和装置，用于通过使用具有小样品尺寸的刚性悬挂的探针和通过使用用于支撑待测液体的容器的顶部负载平衡来测量探针力来确定液体的表面张力或两种不同液体之间的界面张力 。 当使用小容器中的小样品尺寸时，探头和容器壁之间的毛细作用增强了测量的力，并且必须应用毛细作用的调节因子。 刚性悬挂以克服探针和墙壁之间的毛细作用的探针允许这种测量。 对于任何尺寸的样品，根据Isaac Newton在物体之间作用的相等和相反力的第三定律，从液体垂直提起探头所需的力等于液体和容器重量的减少。 因此，使用用于观察重量变化的顶部载荷平衡来确定力的大小，无论是在液体中，而适当配置的探针从液体中取出，或者在由搁置在顶部装载平衡上的方向转换器悬挂的探针中，而容器和 液体降低。

摘要： A method for selectively plugging the more permeable regions of an underground formation having non-uniform permeability wherein a first surfactant solution is injected into the formation in an amount effective to contact a substantial portion of the surface area of the highly permeable regions of the formation, which first surfactant solution is characterized as having a selected chromatographic velocity and as being capable of reversibly adsorbing onto the surface of the pores of the formation.After injecting the first surfactant solution, a water-soluble spacer fluid is injected in an amount sufficient to place the first surfactant solution a selected distant into the formation, the spacer fluid being characterized as having a pre-injection viscosity about equal to the first surfactant solution.After injecting the space fluid, a second surfactant solution is injected in an amount about equal to the amount of the first surfactant solution, and characterized as having a pre-injection viscosity about equal to the first surfactant solution and the spacer fluid, and as having a selected chromatographic velocity which is higher than the chromatographic velocity of the first surfactant solution, and has having a composition such that it will be capable of interacting physically with the first surfactant solution to produce a phase change so that the product of such interaction is capable of at least partially plugging the pores of the formation in which such product is placed.

摘要： A method for adsorbing VCM from vapors through the use of incompletely dried activated carbon under essentially adiabatic conditions allowing most of the VCM to adsorb on carbon having water previously adsorbed, the heat of adsorption of VCM desorbing the water instead of heating the carbon bed. The VCM adsorption is greater than that found on a dry bed when an adiabatic temperature rise is allowed to occur on the dry bed. A portion of the carbon bed can be kept dry if necessary to reach desired VCM levels. The advantage of the invention resides in adsorbing greater amounts of VCM per pound of carbon used, less drying necessary after regeneration, and less likelihood of high temperature deleterious reactions occurring.

摘要： High pressure methylation of 2,6-xylenol to produce 2,3,6-trimethylphenol is accomplished by maintaining the methanol/2,6-xylenol feed at temperature and pressures sufficient to keep the feed liquid in a reactor head then forcing the feed through orifices, expanding the feed into a mixed vapor liquid phase, the feed after expansion being in the range of reaction conditions of pressure and temperature while in the presence of the catalyst where the reaction takes place. The process avoids the current problems of uneven feed mixtures and catalyst tube plugging.
