Absolute cross-sections have been measured for electron-impact dissociative excitation and ionization of 
leading to formation of singly-charged fragments (CD2+, CH+, C+,
H2+ and D+). The animated crossed-beams method is applied in the energy range from the reaction threshold up to 2.5 keV. The maximum cross-sections are found to be (14.0±1.0)×10-17 cm2, (6.5± 0.7)×10-17 cm2, (3.3± 0.3)×10-17 cm2, (1.1±0.1)×10-17 cm2 and (14.0± 1.3)×10-17 cm2 for CD2+, CH+, C+, H2+ and D+, respectively. Individual contributions for dissociative excitation and dissociative ionization are determined for each product as they are indispensable for plasma modelling, diagnostics and data analysis in fusion experiments. Conforming to the scheme recently used in the CD4+ study, the cross-sections are presented in analytic forms suitable for their implementation in plasma simulation codes. Kinetic-energy-release distributions are determined for each product at selected electron energies.
