Each compound has different characteristics, and only by selecting the characteristics of the compound suitable for a specific situation can the compound be applied on a large scale. 123-95-5, name is Butyl stearate, This compound has unique chemical properties. The synthetic route is as follows., Recommanded Product: 123-95-5
An esterification reaction mixture (94 g), consisting of butanol (ca., 4.9% w/w), butyl stearate (95.1% w/w), residual stearic acid (trace), residual methanesulfonic acid catalyst (1383 ppm) and undesired butyl methanesulfonate (613 ppm) was treated with 45% aqueous KOH (229 mg, 1.84 mmol as compared to 1.74 mmol MSA originally charged to the reaction). The resulting mixture was heating at 50 C. for 40 minutes. Without wishing to be bound by any particular theory or explanation, it is believed that reaction of butyl stearate with KOH produced potassium stearate, which retains significant solubility in the butyl stearate medium. The formed potassium stearate then reacted with butyl methanesulfonate to produce potassium methanesulfonate and butyl stearate. After filtration of the by-product solid salts (0.6325 g), analysis of the mixture by gas chromatography revealed only 300 ppm unreacted butyl methanesulfonate, a 51% reduction. Repetition of the above KOH treatment at a higher temperature (175 C./60 min.) revealed complete reaction of the butyl methanesulfonate. Similarly, treatment with NaOH was found equally effective as treatment with KOH. Treatment with Ca(OH)2 proved ineffective, presumably due to formation of poorly soluble calcium salts. Treatment with acidic tin(II) or zirconium (IV) salts resulted in formation of additional butyl methanesulfonate.
According to the analysis of related databases, 123-95-5, the application of this compound in the production field has become more and more popular.
