Coloration of fibrin fabric with berberine natural dye with ultrasonic technique using ZnO nano powder as light fastness improving was written by Kamel, M. M.;Mashaly, Hamada M.. And the article was included in World Applied Sciences Journal in 2013.Category: chlorides-buliding-blocks The following contents are mentioned in the article:
Berberine, a natural cationic colorant, is the major component of Amur Cork tree extract was used as a natural basic dye since the synthetic basic dyes remarked high acute and chronic toxicity on human beings, carcinogenic effect on animals, in addition to a hazardous effect on aquatic marines. These factors brightened the scope to carry out this research, by making a comparative dyeing study by ultrasonic and conventional heating techniques on anionized fibrin fabrics with the berberine dye. It is found that the performance of ZnO nano particles as UV-absorbers can be efficiently transferred to fabric materials. The UV tests indicate a significant improvement in the UV absorbing activity in the ZnO-treated fabrics. This study involved multiple reactions and reactants, such as 4,6-Dichloro-N-phenyl-1,3,5-triazin-2-amine (cas: 2272-40-4Category: chlorides-buliding-blocks).
4,6-Dichloro-N-phenyl-1,3,5-triazin-2-amine (cas: 2272-40-4) belongs to organic chlorides. Chlorinated organic compounds are found in nearly every class of biomolecules and natural products including alkaloids, terpenes, amino acids, flavonoids, steroids, and fatty acids. The haloform reaction, using chlorine and sodium hydroxide, is also able to generate alkyl halides from methyl ketones, and related compounds. Chloroform was formerly produced thus.Category: chlorides-buliding-blocks
