1,5-Diisopropylnaphthalene(CAS: 38640-62-9)

1,5-Diisopropylnaphthalene (CAS: 38640-62-9) is a white crystalline solid with a melting point of 61-62°C. Its molecular weight is approximately 264.45 g/mol. It is slightly soluble in water but soluble in organic solvents like ethanol and acetone. It is moderately reactive with oxidizing agents and mild bases. It has low volatility and ignites at 400-420°C.

1,5-Diisopropylnaphthalene is typically synthesized by the direct alkylation of naphthalene with isopropanol in the presence of a strong acid catalyst such as hydrogen chloride (HCl). The reaction is performed at elevated temperatures (120-150°C) to achieve a yield of about 70-80%. Selectivity towards the desired product is around 90%.

1,5-Diisopropylnaphthalene (CAS: 38640-62-9) is used in the pharmaceutical industry for the synthesis of certain drugs, in the polymer industry for the manufacture of resins, in the semiconductor industry for the production of electronic materials, and in the chemical sensor industry for gas detection applications.

When handling 1,5-Diisopropylnaphthalene (CAS: 38640-62-9), gloves and safety glasses should be worn. Store in a fume hood to minimize inhalation risk. Avoid contact with eyes and skin. In case of spill, use appropriate PPE and follow the Material Safety Data Sheet (MSDS) for cleanup instructions. Ensure proper ventilation and disposal according to local regulations.
