  • PROCESS FOR PREPARING ALKYL SALICYLIC ACID AND PRODUCTS THEREOF
    Publication number: 20190016660
    Abstract: This invention relates to a process for preparing an alkylsalicylic acid. The process comprises reacting salicylic acid with an olefin having at least four carbon atoms at a temperature ranging from about 50° C. to about 200° C. in the presence of an arylsulfonic acid-containing catalyst (such as para-toluene sulfonic acid), to produce an alkylsalicylic acid. The resulting alkylsalicylic acid has various applications such as a food preservative, an oil field chemical for oil recovery, and a component in a color toner agent for electrophotography.
