반응 단계
It has also been observed, in accordance with another aspect of the present invention, that a mixture of halogen and alkali metal hydroxide i.e. an alkali metal hypohalide such as sodium hypochlorite, hypobromite or hypoiodite when it is added to an aqueous suspension of 5-nitro-2-formyl-thiophene maintained at a pH between 4.5 and 6.5 by means of acetic acid or an acetic acid/alkali metal acetate mixture, provides pure 5-nitro-2-thenoic acid in a yield of at least 75%.
