 Full text | Abstract: This contribution/study deals with partial hydrophobisation of O-(carboxymethyl)starches (CMS, DS = 0.1 and 0.3) with alkylamine (C6, C10, and C12). The reaction was performed in methanol and dimethylsulfoxide with Dimethylaminopyridine(DMAP) as catalyst under classical heating and compared to the reaction performed with the assistance of microwave energy. The derivatives obtained were characterised by FT-IR spectroscopy and elemental analysis. Surface-activity and functional properties related to their application in textile finishing and the laundry process - washing power and antiredepositive efficiency were studied. Some of the tested derivates exhibited excellent emulsifying efficiency and detergent performance properties. |
