Solid structures of different shapes, hydrogen chloride, and a small number of liquid products are formed from chloromethanes (CH2Cl2 and CHCl3) and binary systems with triphenylphosphine (CH2Cl2 + PPh3, CHCl3 + PPh3, and CCl4 + PPh3) under the action of a liquid‐phase low‐voltage discharge (60‐V DC). It is observed that triphenylphosphine additives sharply increase the reactivity of CCl4. Besides, a quantum chemical simulation of chloromethane transformation mechanism in the binary systems with triphenylphosphine is conducted, together with the likely mechanism of chloromethane conversion into active particles under the action of a liquid‐phase low‐voltage pulsed discharge.

Thiophene and 3‐methyl‐2‐thiophenecarboxaldehyde conversion by direct liquid phase discharges has been experimentally studied. The voltage was limited to 40 V. The main products of conversion, determined by GC and GC‐MS methods, for thiophene were: acetylene, carbon disulfide, soot, and hydrogen; for 3‐methyl‐2‐thiophenecarboxaldehyde—carbon disulfide, acetylene, soot, carbon dioxide, hydrogen, and diacetylene. Schemes of fragmentation of these heterocyclic compounds under the action of low‐voltage discharges are proposed.
