FIELD: chemistry, chemical technology. ^ SUBSTANCE: invention relates to cross-linking compositions for hydrocarbon fuels. A cross-linking agent comprises composition consisting of lithium alcoholate of the general formula: LiOR1 wherein R1 means (C3-C6)-hydrocarbon radical of direct or iso-structure and boron alkoxide-base compounds as ester of the formula: Bn(OR2)m(O2R3)n-1 wherein at n = 2, m = 4 and at n = 3, m = 5 and at n = 4, m = 6 R2 means (C4-C16)-hydrocarbon radical of direct structure; R3 means (C4-C20-hydrocarbon radical of direct or iso-structure, or (C4-C20)-hydrocarbon radical comprising at least one heteroatom of oxygen or nitrogen in the chain. The mole ratio of indicated boron alkoxide-base compound to lithium alcoholate in the composition = 1:(1-4), respectively. Invention provides enhancing effectiveness of cross-linking properties of the cross-linking agent based on elevated mechanical strength of gel and reducing time for cross-linking formation. ^ EFFECT: improved and valuable technical properties of agent. ^ 3 cl, 1 tbl |
