Description
OP CATECHOL novel namely The invention also relates to process for the solid state mination of catecholf to result in desired Other and further features of invention will apparent The novel is of value in organic synthesis as starting compound for the preparation of other It is of value as intermediate for the preparation of the corresponding quinone which is of value as hydrogen dehydrogenation agent and which can also be used complex As compared with the bromination in used in the art for the preparation of similar state bromination has a number of Plant capacity is substantially larger and the equipment used is As compared with bromination in the difficulty of the removal of hydrogen bromide and the corrosivity at distillation temperature of hydrogen bromide are as no solvents are used during The novel process comprises brominating chol with a predetermined quantity of advantageously at ambient removing at the end of the reaction excess of and if recrystallizin the product from a suitable The following example the present of A quantity of g catechol was brominated by the addition cf g bromine ratio at ambient After 24 hours excess of bromine was sucked off at reduced pressure and the product was recrystallized from a ether mixture ratio The was in fom yellow yield 33 8 Br C Br shows peaks at and and insufficientOCRQuality
