よくある質問 — 技術・供給について

• 質問:

  ジフェニルスルフィド CAS 139-66-2はジフェニルジスルフィドと同じ製品ですか？

  回答: No. Diphenyl Sulfide contains one sulfur atom linking two phenyl groups, while Diphenyl Disulfide, CAS 882-33-7, contains an S-S bond. State the full product name and CAS to avoid substitution.
• 質問:

  ジフェニルスルフィドの用途は何ですか？

  回答: It is used as an intermediate for pesticides, pharmaceuticals, dyes and specialty sulfur-containing chemicals. The required purity and sulfur-related impurity limits depend on the downstream reaction.
• 質問:

  ジフェニルスルフィドではどのバッチデータを合意すべきですか？

  回答: Agree the GC assay and test method, water, color and clarity, density or refractive index, plus any impurity limits required by the downstream reaction. Compare values on the same basis when reviewing offers.
• 質問:

  ジフェニルスルフィドにはどのような取扱い・安全管理が適用されますか？

  回答: Diphenyl Sulfide is toxic and can be absorbed by ingestion, inhalation or skin contact, so use closed transfer, ventilation and chemical-resistant PPE. Store sealed in a cool, compatible area and avoid uncontrolled release.
• 質問:

  What physical properties identify Diphenyl Sulfide?

  回答: Diphenyl Sulfide is a colorless to yellowish liquid with melting point around -40 C, boiling point around 295-296 C and density about 1.113 g/cm3. It is insoluble in water, so water content and clarity should be checked against the specification.
