WebDiisononyl cyclohexane-1,2-dicarboxylate [166412-78-8] The isomeric mixture of diisononyl cyclohexane-1,2-dicarboxylate (trade name Hexamoll DINCH®)isacolourless, clear liquid with an odour that is barely dis- cernible (empirical formula C26H48O4,molar mass 424.7 g/mol, melting point – 54°C, boiling point 240–250°C at 7mbar). WebAug 15, 2024 · The molecular ions are energetically unstable, and some of them will break up into smaller pieces. The simplest case is that a molecular ion breaks into two parts - one of which is another positive ion, and the other is an uncharged free radical. (1) M ⋅ + → X + + Y ⋅ The uncharged free radical won't produce a line on the mass spectrum. malcolm d. evans international law
