    摘要： Problem to be Solved It is intended to provide an industrially preferable fluoroalkylating agent and use thereof. Solution The present invention provides a fluoroalkylating agent represented by the general formula (1) wherein R 1 is a C1 to C8 fluoroalkyl group; R 2 and R 3 are each independently a C1 to C12 alkyl group or the like; Y 1 to Y 4 are each independently a hydrogen atom, a halogen atom, or the like; and X - is a monovalent anion. A compound of the general formula (3): R 4 -S-R 1 having an introduced C1 to C8 fluoroalkyl group is easily obtained by reacting a compound of the general formula (2): R 4 -S-Z wherein R 4 is a hydrocarbon group or the like; and Z is a leaving group, with the compound of the general formula (1).

    摘要： The invention relates to a process for producing monopentaerythritol of high purity and monopentaerythritol produced by the process. Formaldehyde is reacted with acetaldehyde in an aqueous solution in the presence of a strongly basic hydroxide in a conventional way. The obtained reaction mixture is evaporated to a dryness of 50-70 % by weight and is thereafter cooled. Crystals of pentaerythritol thereby formed are separated off. The crystals are dissolved in water or in a water-containing mother liquor containing pentaerythritol to a dryness of 35-55 % by weight. The solution is treated in a purification step whereupon monopentaerythritol of high purity is crystallized at a temperature of 40-90 °C and separated from the remaining mother liquor which is recirculated to the above mentioned step.
