Mao, Faming published the artcileSynthesis of reactive scarlet 3G, Category: chlorides-buliding-blocks, the publication is Ranliao Yu Ranse (2010), 47(1), 19-20, database is CAplus.
Reactive scarlet 3G was prepared from sodium 2,4-diaminobenzenesulfonate, 2,3-dibromopropanoyl chloride and γ acid by acylation, diazotization, coupling and salting-out. The two steps of acylation were studied emphatically. The complete reaction conditions were obtained by experiments: the temperature of acylation was 0-15°C, pH was controlled between 5-7.5; the molar ratio of 2, 3-dibromopropanoyl chloride and sodium 2,4-diaminobenzenesulfonate was 1.05: 1,2,3-dibromopropanoyl chloride and γ acid molar ratio was 1.05: 1. The yield of acylation was above 90%.
Ranliao Yu Ranse published new progress about 18791-02-1. 18791-02-1 belongs to chlorides-buliding-blocks, auxiliary class Aliphatic Chain, name is 2,3-Dibromopropionylchloride, and the molecular formula is C3H3Br2ClO, Category: chlorides-buliding-blocks.
