    摘要: Processes for producing a hydroxyalkyl(meth)acrylate which comprise reacting (meth)acrylic acid with an alkylene oxide in the presence of a catalyst. A first process is characterized in that the amount of the acid ingredient is kept, on calculation, at 0.010 or more in terms of molar ratio to the catalyst present in the liquid reaction mixture and that the liquid reaction mixture from which the hydroxyalkyl(meth)acrylate has been distilled off is used in the subsequent reaction. A second process is characterized in that a dialkylene glycol mono(meth)acylate is supplied to the reaction system to cause the dialkyleneglycol mono(meth)acylate to coexist in the liquid reaction mixture.

    摘要: The present invention provides a novel production process for a hydroxyalkyl (meth)acrylate, in which it is possible that: in a batch reaction system, the amount of the hydroxyalkyl (meth)acrylate (which is the objective product) as produced is kept nearly on the same level as conventional and further, at the same time, there is suppressed the side production of the alkylene oxide's diaddition product (dialkylene glycol mono(meth)acrylate) that lowers the purity of the product to thus give a bad influence upon its quality. The present invention production process comprises the step of carrying out a batch reaction between (meth)acrylic acid and an alkylene oxide in the presence of a catalyst in order to produce the hydroxyalkyl (meth)acrylate; with the production process being characterized by arranging that the reaction should be initiated in a state of a catalyst concentration of more than 1, wherein the catalyst concentration is defined as the amount of the catalyst as used relative to the integrated amount of the (meth)acrylic acid as supplied and is assumed to be 1 in terms of the amount of the entire catalyst to be used relative to the amount of the entire (meth)acrylic acid to be supplied.

    摘要: It is an object of the present invention to provide a membrane separation apparatus and a membrane separation process that are unlikely to cause membrane fouling and plugging, capable of achieving membrane separation even with relatively low flow rate of water, have an excellent membrane packing density, and are unlikely to cause deposition of foreign components in the apparatus. In order to achieve the above object, according to the present invention, vessel-type inner casings are disposed in a pressure vessel along the longitudinal axis thereof, in which the pressure vessel has a water inlet at a first end and a concentrate outlet at a second end. A flow-regulating plate is disposed on the side of the water inlet of the pressure vessel. Stacks of membrane separation units are respectively disposed in the inner casings, and spacers are disposed between the adjacent membrane separation elements. The spacers also serve as sealing members. Each stack of the membrane separation units and the spacers together define a through-hole extending from a first side to a second side, of the stack of the membrane separation elements. The inner casings have permeate discharge passages along the longitudinal axis thereof. The permeate discharge passages are communicated with the through-hole of each stack of the membrane separation elements. Water that has been fed into the pressure vessel via the flow-regulating plate permeates through the membrane separation elements and is discharged to the outside via the through-holes and the permeate discharge passages.
