Huang, Liang-chen published the artcileAroma finishing of silk fabric grafted with α-bromoacrylamidoethyl cyclodextrin, Quality Control of 18791-02-1, the publication is Yinran (2009), 35(17), 5-9, database is CAplus.
α-Bromoacrylamidoethyl cyclodextrin (β-CD-2-EDBA) was prepared with β-cyclodextrin, p-toluenesulfonyl chloride and 2,3-dibromo-propionyl chloride. Aroma finishing of silk fabric grafted with 8-CD-2-EDBA was carried out. Optimum grafting process was pH value 9, grafting agent 16% (owf), sodium sulfate 8 g/L, liquor ratio 1:50, and treating at 90°C for 40 min. Grafting ratio of treated silk fabric was high, and fragrance storage and fragrance retention time enhanced significantly. Scanning electron microscope picture proved that B-CD-2-EDBA was successfully grafted onto silk surface. Grafting ratio was tested with phenolphthalein spectral probe method and gravimetric method sep., it was found that the former had higher grafting ratio, while the latter was more accurate.
Yinran 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, Quality Control of 18791-02-1.
