Application:
N-Butyllithium solution is mostly used as a pharmaceutical intermediate to synthesize anionic polymerization initiator. It is also used to produce rubber (such as integral rubber SIBR, which is the most versatile diene rubber to date), fragrance, liquid crystal materials, and other industries. It is a chemical product intermediate, linking agent, alkylating agent, and polymerization catalyst. As a catalyst, N-Butyllithium is widely used as a pharmaceutical intermediate, liquid crystal monomer, and pesticide production catalyst.
N-Butyllithium is also widely used in organic syntheses, especially in growing carbon chains, and it is a staple laboratory product in reactions such as:
1) Metallization reaction: R-H + n-Butyl-Li → R-Li + Butane, in which the produced lithium alkyl can react with many substances.
2) Direct metallization: the aromatic compound that connects the substitute reacts with N-Butyllithium, and lithium metal can be attached to the aromatic compound.
3) Nucleophilic addition and substitution reaction.
4) Halogen-metal replacement.
Storage:
Store in cool place. Keep container tightly closed in a dry and well-ventilated place.
