Catalytic system for preparation of high branched alkane from olefins

An oily alkane mixture prepared by the following steps:

• (a) catalyzing ethylene polymerization in the presence of (1) a catalyst comprising one or more complex(es);
• and (2) a cocatalyst comprising one or more alkyl aluminum reagents, thereby forming an oily highly branched polyethylene;
• (b) hydrogenating the oily highly branched polyethylene in the presence of a reduction catalyst;
• wherein each of said one or more complex(es) independently comprises one or more salt(s), wherein each of said one or more salt(s) independently comprises a compound of formula I and one or more divalent metal(s) selected from the group consisting of nickel, palladium and a combination thereof;
• wherein,
• Z is hydrogen, C1-C4 alkyl, C1-C4 haloalkyl, or unsubstituted or substituted phenyl;
• Y is unsubstituted or substituted phenyl;
• or Z and Y are combined with the adjacent carbon atom to form an unsubstituted or substituted acenaphthyl, phenanthryl, or C5-C8 cycloalkyl, wherein each of the substituted phenyl, acenaphthyl, phenanthryl or cycloalkyl independently has 1 to 5 substituents selected from the group consisting of halogen, C1-C4 alkyl, and C1-C4 haloalkyl;
• R1 and R2 are independently H, halogen, C1-C8 alkyl, C1-C8 haloalkyl, unsubstituted or substituted phenyl, —O—Ra, —CH2—O—Ra, —SRb, or —CH2—S—Rb, wherein Ra and Rb are independently C1-C8 alkyl or unsubstituted or substituted phenyl;
• R3 and R4 are independently H, halogen, C1-C8 haloalkyl, —O—Ra, —CH2—O—Ra, —SRb, or —CH2—S—Rb;
• of R1, R2, R3 and R4, R1≠(R3 and R4) and/or R2≠(R3 and R4) and each substituted phenyl independently has 1 to 5 substituents selected from the group consisting of halogen, C1-C4 alkyl, and C1-C4 haloalkyl;
• and
• R5, R6 and R7 are independently halogen, nitro, hydrogen, C1-C8 alkyl, C1-C8 haloalkyl, —O—Ra, or —CH2—O—Ra;
• and
• wherein the oily alkane mixture comprises an oily alkane having a structure of R8R9CH(CH2)n, CHR10R11 or R8R9R10C(CH2)nCR10R11R12;
• wherein each R8-R12 independently has a structure of R13R14CH(CH2)mCHR15R16 or R13R14R15C(CH2)nCR15R16R17;
• wherein each R13-R17 independently has a structure of R18R19CH(CH2)xCHR20R21 or R18R19R20C(CH2)xCR20R21R22;
• wherein each R18-R22 is independently hydrogen or a straight-chain or branched-chain alkane;
• and wherein n, m, and x are each independently an integer from 1-100.
