preparation example 1

[0102]

[0103] A 50% aqueous solution (manufactured by Nippon Chemical Industry Co., Ltd.) of tri-n-butyl-n-hexadecylphosphonium chloride (1,783 g (1.924 mol)) was diluted with 9 L of ion-exchanged water. 222.0 g (2.024 mol) of sodium borofluoride (manufactured by Morita Chemical Industry Co., Ltd.) was dissolved in 1 L of ion-exchanged water. After filtering the insoluble matter with filter paper, it added dropwise at room temperature (15 degreeC) to the phosphonium salt aqueous solution. After the dropwise addition was completed, it was aged at room temperature (25° C.) for 60 minutes.

[0104] Next, the resulting slurry was filtered with a centrifuge. 6 L of ion-exchanged water was added to the filtered crystals, stirred at room temperature for 15 minutes, and then filtered with a centrifuge. The filtrate was titrated with an aqueous silver nitrate solution, and the slurry was washed and refiltered repeatedly until the halogen was negative.

[0105] Then, it dried at ...

[0116]

[0117] Except using 50% aqueous solution of 2779.3 g (3.0 moles) of tri-n-butyl-n-hexadecylphosphonium chloride and replacing sodium borofluoride with 579.8 g (3.15 moles) of potassium fluoride phosphate, the same procedure as in Preparation Example 1 was carried out. The operation obtained tri-n-butyl n-hexadecylphosphonium 6 phosphorus fluoride.

Abstract

The present invention provides an antistatic agents for resins, containing phosphonium salts represented by the general formula (1): (1) wherein R<1>, R<2>, and R<3> are each straight-chain or branched alkyl having 3 to 8 carbon atoms, and R<4> is straight-chain or branched alkyl having 10 to 22 carbon atoms, each alkyl being optionally substituted with hydroxyl or alkoxyl; R<1>, R<2>, and R<3> may be the same or different from each another; and X<-> is a tetrafluoroborate ion or a hexafluorophosphate ion.

Description

technical field [0001] The present invention relates to a phosphonium salt antistatic agent, an antistatic resin composition containing it, and an antistatic resin molded article. Background technique [0002] Conventionally, resins have been used for various purposes depending on their properties. For example, polyamide resins such as nylon-6, nylon-6,6, nylon-12, and copolymerized nylon are widely used as clothing materials, and due to excellent thermal properties, mechanical properties, chemical properties, etc., are also widely used as engineering plastics. In addition, for example, polyester resins represented by polyethylene terephthalate are used in plastic bottles (including PET bottles for beverages), fibers, films (including photographic film), cloth, non-woven fabrics, and adhesives, especially polyester films, are also widely used for magnetic cards such as credit cards. Contents of the invention [0003] However, these resins are generally electrically insu...
