GC/MS IDENTIFICATION OF NONYLPHENOL ETHOXYLATES IN PRЕPARATE OP,10 AND ITS PHOTOOZONATION PRODUCTS

 , GC/MS identification of nonylphenol ethoxylates of preparate OP,10 and its intermediate photoozonation products – ethylene glycols and propylene glycols with decreasing ethylene oxide (EO) and propylene oxide (PO) chain length using relationship of fragmentation of electron impact ionization of these classe compounds was carried out. Compounds with following molecular weight were identified: nonylphenol ethoxylates – 220+44·m (m=1–12), ethylene glycols – 18+44·m (m=2– 10) and propylene glycols – 18+58·p (p=4–8), where m and p – varying EO and PO units respectively.

Keywords: identification of nonylphenol ethoxylates, preparate OP,10, photoozonation products, GC/MS
