| titleOfInvention | Environmentally friendly process for 3,5-dibromo-4-hydroxybenzonitrile |
| abstract | From 4-hydroxybenzonitrile, using environmentally friendly bromination reagents containing a 2: 1 molar ratio of bromide and bromate without any catalyst in an aqueous acidic medium under ambient conditions, without any finishing procedure Highly pure 3,5-dibromo-4-hydroxybenzonitrile (bromoxynyl) was prepared in high yield. The product 3,5-dibromo-4-hydroxybenzonitrile, which had a melting point of 189-191 ° C. and no purification was higher than 99% by gas chromatographic analysis, was obtained in a yield of 91-99%. [Selection figure] None |
