  • Patent number: 10683250
    Abstract: The invention relates to an improved manufacturing process for the preparation of high 2,4?-dihydroxydiphenylmethane, by a process involving reaction of phenol and formaldehyde, in the presence of an inorganic polyprotic acid. According to this process, the reaction conditions are selected to favour a high yield of dihydroxydiphenylmethane, with a relatively high concentration of the 2,4?-isomer, by using a relatively low molar excess of phenol than conventional methods.
