Dibutyl ether is a chemical compound belonging to the ether family with the molecular formula of C₈H₁₈O. It is colorless, volatile, and flammable liquid and has peculiar ethereal smell. Liquid dibutyl ether is lighter than water. On the other hand, the vapor is heavier than air. It is not soluble in water, but it is soluble in acetone and many other organic solvents. Due to this property, dibutyl ether is used as solvent in various chemical reactions and processes. For example, phenyllithium is commercially available as a ca. 1.8 M solution in dibutyl ether.
A method for purifying trimethoxy (pentamethylcyclopentadienyl) titanium
PendingCN122325516APentamethylcyclopentadieneHeptadecane
This invention belongs to the field of chemical production technology, specifically disclosing a purification method for trimethoxy(pentamethylcyclopentadienyl)titanium, comprising the following steps: vacuum distillation of crude trimethoxy(pentamethylcyclopentadienyl)titanium raw material to obtain a crude distillate; adding 5-20 parts by mass of a modifier to 100 parts by mass of the crude distillate, wherein the modifier is at least one selected from triethylene glycol dibutyl ether, tetraethylene glycol dibutyl ether, n-heptadecane, n-octadecane, and mineral oil, and then distilling to obtain the product. This invention achieves large-scale purification of Star-Ti, achieving a distillation yield of over 75%, with a maximum of over 95%, and obtaining a high-purity product with an organic purity of over 99.5%, solving the problems of difficult large-scale purification, difficulty in purity improvement, and low recovery rate of Star-Ti in existing technologies.
