The preparation of ester heterocycles mostly uses heteroatoms as nucleophilic sites, which are achieved by intramolecular substitution or addition reactions. Compound: 3,3-Bis(3,5-dibromo-4-hydroxy-2-methylphenyl)-3H-benzo[c][1,2]oxathiole 1,1-dioxide( cas:76-60-8 ) is researched.Application of 76-60-8.Stojkoski, Viktor; Kert, Mateja published the article 《Design of pH responsive textile as a sensor material for acid rain》 about this compound( cas:76-60-8 ) in Polymers (Basel, Switzerland). Keywords: pH sensitive dye rainwater acid rain sensor air pollution; acid rain; bromocresol green; pH sensitive dyes; polyamide 6; water and oil repellency. Let’s learn more about this compound (cas:76-60-8).
The chem. composition of rainwater can serve as an indicator of the excess of acidifying air pollutants. The pH value of rainwater in the presence of sulfur dioxide and nitrogen oxides, the precursors of acid rain, falls below pH 5.6, which is the limit value for acid rain. In this research, the tailoring of halochromic textile was examined for the design of a functional textile that can serve as a sensor and inform the wearer about the presence of pollutants in the air by means of an immediate color change. For this purpose, a polyamide 6 fabric was dyed with the pH-sensitive Bromocresol green dye, which causes a color change below pH 3.6 (yellow) and above pH 5.4 (blue). In addition, the dyed polyamide 6 fabric was treated with a water and oil repellent finish. Color and color change before and after immersion of unfinished and finished dyed samples in buffer solutions with different pH values were evaluated spectrophotometrically using the CIELAB color space. The color fastness to rubbing, washing, and light, and the water and oil repellency of the dyed fabrics were determined according to valid SIST EN ISO standards The results showed that the unfinished dyed polyamide 6 fabric undergoes a reversible color change faster and more clearly than the finished dyed polyamide 6 fabric. The dyed polyamide 6 fabric had good color fastness to rubbing and domestic and com. laundering, while the color fastness to light was poor. In addition, the dyed polyamide 6 fabric was pH-sensitive, despite dye degradation under xenon light, regardless of whether it was finished.
This literature about this compound(76-60-8)Application of 76-60-8has given us a lot of inspiration, and I hope that the research on this compound(3,3-Bis(3,5-dibromo-4-hydroxy-2-methylphenyl)-3H-benzo[c][1,2]oxathiole 1,1-dioxide) can be further advanced. Maybe we can get more compounds in a similar way.
