| titleOfInvention | Process for the production of long-chain cis- and trans-2-alkyl-5-hydroxy-1,3-dioxanes |
| abstract | A method of producing long-chainncis-2-alkyl-5-hydroxy-1,3-dioxanes of generalnformula 1 and trans-2-alkyl-5-hydroxy-1,3-ndioxanes of general formula II, in which nnis a number from 7 to 13, characterized in thatnThe transacetalization reaction undergoes a four-component reactionnmixtures of cis-2-alkyl-5-hydroxy-1,3-dioxanenwith the general formula 1,ntrans-2-alkyl-5-hydroxy-1,3-dioxane of generalnFormula 2, cis-2-alkyl-4-hydroxymethyl-1,3-dioxolanenof general formula 3 andntrans-2-alkyl-4-hydroxymethyl-1,3-dioxolennu of general formula 4, where n is abovengiven meaning, in the presence of a catalystnacidic, preferably p-toluenesulfonic acid monohydrate,nin a mixture of solventsnhexane and benzene, containing fromn0 to 40% by volume of benzene, first innroom temperature and then at temperaturenfrom 273 to 278 K, and crystallizednmixtures of 1,3-dioxane derivatives are separatednup and subjected to fractionation distillation. |
