说明

硝酸铝九水合物是一种铝盐,可以通过将铝或氢氧化铝溶解在稀硝酸中来制备。它用于制备绝缘纸、变压器铁芯层压板和阴极射线管加热元件。

一般描述

Aluminum nitrate nonahydrate is an aluminum salt that can be prepared by dissolving aluminum or aluminum hydroxide in dilute nitric acid. It is used in the preparation of insulating papers, transformer core laminates, and cathode-ray tube heating elements.
 

应用

Aluminum nitrate nonahydrate can be used as a catalyst to synthesize:
  • β-Amino carbonyl compounds via one-pot Mannich reaction.
  • Bis(indolyl)methanes via electrophilic substitution reaction of indoles with aromatic aldehydes.
  • 3,4-Dihydropyrimidinones via solvent-free Biginelli reaction.

特点和优势

  • Easily recoverable through simple phase separation
  • Reusable without a distinct loss of catalytic activity
