| titleOfInvention | Nitrosamine/nitrite inhibition in tertiary alkylamine oxide compositions |
| abstract | The invention relates to a method for the production of tertiary amine oxides with and prevented and/or reduced nitrosamine formation and/or reduced nitrite formation, comprising the steps of: during or after the production of the aforementioned tertiary amine oxide, adding a mixture comprising a poiyamino methylene phosphonate of formula (I) wherein n=2-1500, M is hydrogen or a cation selected from alkali metals, alkaline earth metals and ammonium, and the R groups are the same or different from one another with at least one R group different from CH2PO3M2 and selected from the following classes: 1) CH2PO3M2 2) CH2R' R'=CH2OH; CHOHCH3; CHOHCH2CI or CHOHCH2OH; 3) (CH2)nSO3M wherein n=3+4 4) CH2CH2R" wherein R"=CONH2, CHO, COOR1, COOX or CN; where R1=CH3+CH2H5; wherein X is hydrogen or an alkali metal or ammonium cation. The invention also relates to tertiary amine oxide composition with improved nitrosamine contents and/or nitrite contents; as well as use of the aforementioned polyamino methylene phosphonates as nitrosamine inhibitor and/or as nitrite inhibitor. |
