Studies of the Purolite CT151DRY alkylation catalyst by Purolite in the phenol alkylation reaction of ethylene oligomers of the C16-C18 fraction

Abstract

The possibility of using a Purolite alkylation catalyst of the CT151DRY brand in the reaction of alkylation of phenol with ethylene oligomers of the C16-C18 fraction to obtain the target alkylphenol, which is a semi-product in the production of multifunctional additives to lubricants is considered in the article. It is shown that the Purolite CT151DRY catalyst is resistant to mechanical influences and high temperatures within the studied range up to 180 °C and the synthesis duration up to 50 hours while maintaining a high alkylating ability in the reaction of phenol alkylation by ethylene oligomers of the C16-C18 fraction and is highly sensitive to changes in the composition of raw materials and the change of raw ethylene oligomers. The Purolite CT151DRY catalyst has an alkylating ability comparable to other catalysts and can be recommended to obtain the target alkylphenol.
