| LogP | 3.97 at 20℃ |
| NIST chemical information | information provided by: webbook.nist.gov (external link) |
| EPA chemical substance information | information provided by: ofmpeb.epa.gov (external link) |
| Use | an intermediate in organic synthesis for the synthesis of 1-naphthyl aldehyde. used in synthetic resin, medicine, etc. |
| production method | prepared by chloromethylation of naphthalene. The naphthalene, paraformaldehyde, glacial acetic acid, 85% Phosphoric acid and concentrated hydrochloric acid were heated to 85 degrees C, vigorously stirred 6H. After completion of the reaction, it was cooled to 15 °c and washed with water. Finally, it was washed with 10% potassium carbonate solution, the aqueous layer was separated, ether was added, and dried with anhydrous sodium carbonate. The ether was then distilled off under atmospheric pressure, and the remainder was distilled under reduced pressure to collect a 128-135 ° C. (0.67kPa) fraction to obtain a finished product. In addition, 1-methyl naphthalene chloride can also be prepared. |
