Process of separation and purification of t-butyl-methylphenol isomer

Disclosed is a process of separation and purification of t-butyl-methylphenol isomer from the mixture of t-butylcresols, containing the component 2-t-butyl-4-methylphenol (4M2B), 2-t-butyl-5-methylphenol (3M6B), compounds with the boiling point lower than 4M2B and of the compounds with the boiling points higher than 3MB6 by distillation operations under the temperatures 200°C or less, whilst the mixture of t-butyl cresols is a reaction mixture obtained by butylation reaction of m,p-cresols mixture. Opísaný je spôsob separácie a čistenia izoméru t-butyl-metylfenolu zo zmesi t-butylkrezolov, obsahujúcej zložku 2-t-butyl-4-metylfenol (4M2B), 2-t-butyl-5-metylfenol (3M6B), zlúčeniny s nižším bodom varu ako má 4M2B a zo zlúčenín s vyšším bodom varu ako má 3M6B destilačnými operáciami pri teplote 200 °C alebo nižšej, pričom zmes t-butylkrezolov je reakčnej zmesou získanou butylačnou reakciou zmesi m,p-krezolov.ŕ
