摘要： A method of assembling an apparatus for containing reagents for a chemical reaction. The apparatus includes an elongate housing and a receptacle. The elongate housing may include a cooling means, and end fittings which may include ports where fluids may be introduced and/or removed. Specifically, the method relates to the securement of a receptacle relative to the outwardly facing surface of the housing.

摘要： The present disclosure discloses a catalyst composition for polymerization of an α-olefin and preparation and use thereof. The catalyst composition comprises boron trifluoride and at least one protic cocatalyst; the protic cocatalyst has a structural formula of X—(CH2)n—OH, where n is an integer selected from 1 to 10; X is selected from nitro, halogen, cyano, sulfonic acid group, aldehyde group, acyl, carboxyl and amino. The catalyst can be used in production of a poly(α-olefin) synthetic base oil, and is particularly suitable for a low viscosity poly(α-olefin) synthetic base oil with high selectivity of the target product.

摘要： Macrocyclic polyalkene homopolymers and copolymers can be formed and converted to macrocyclic polyalkanes or macrocyclic poly(alkane-co-alkene) upon hydrogenation or, when the macrocyclic polyalkene is reacted with an alkene in the presence of an olefin metathesis catalyst, to a macrocyclic poly(alkane-co-alkene) comprising vicinal —C(═CR2)—'s. Upon hydrogenation of a macrocyclic poly(alkane-co-alkene) comprising vicinal —C(═CR2)-'s, macrocyclic poly(alkane)s or poly(alkane-co-alkene)s with isolated —C(═CR2)- groups can be provided, depending on the degree of hydrogenation. The poly(alkane-co-alkene)s with isolated —C(═CR2)- units can be used to form poly(macrocyclic poly(alkane-co-alkene))s, poly(macrocyclic poly(alkane))s, and/or bi-, tri-, and/or multi-macrocyclic poly(alkane-co-alkene)s or bi-, tri-, and/or multi-macrocyclic poly(alkane)s.
