FIELD: chemistry.
SUBSTANCE: invention relates to catalytic chemistry. Disclosed are catalysts for alkali-free purification of oil stock in solid or liquid form based on the use of metal compounds of general formula Cu2(OH)3Cl(L1)2-4(L2)1-4, where L1 is an amino alcohol, and L2 is a monoatomic alcohol.
EFFECT: obtaining a catalyst for alkali-free purification of oil stock in solid or liquid form, in which copper (I) chloride is replaced with copper oxychloride.
