Radiolysis of alkylnaphthalene oils

Radiolysis of alkylnaphthalene oils was studied. It was shown that the radiation-chemical yield of hydrogen grows linearly (from 0.26 for KR-007A oil to 0.78 for KR-019 oil) with an increase in the average (with allowance for the composition) length of the alkyl chains. A number of liquid alkanes and alkenes (C₅–C₁₂) along with naphthalene were identified in the radiolysis products. Dimers and polymers make 2–10% depending on the radiation dose. Alkylnaphthalene oils used as additives for synthetic oils of the WM-5 type substantially improve the radiation resistance of these oils.
