DIN EN 13268 Berichtigung 1-2007 表面活性剂.测定乙撑氧和环氧丙烷加合物中乙撑氧和环氧丙烷组群
Surface active agents - Determination of ethylene oxide and propylene oxide groups in ethylene oxide and propylene oxide adducts; German version EN 13268:2001, Corrigenda to DIN EN 13286:2001-07
This European Standard specifies a method for the qualitative and quantitative determination of ethylene oxide and propylene oxide groups in EO and PO adducts, polyethers and polyglycol esters. Note: If a suitable calibration is performed, methoxy groups can also be detected.
