Catalytic oligomerization of olefins

Catalytic oligomerization of olefins. Loveless, Frederick Charles (Uniroyal, Inc., USA). Ger. Offen. DE 2558475 30 Jun 1977, 19 pp. Addn. to Ger. Offen. 2,526,615. (German). (Germany). CODEN: GWXXBX. CLASS: IC: C08F010-00. APPLICATION: DE 75-2558475 24 Dec 1975. DOCUMENT TYPE: Patent CA Section: 35 (Synthetic High Polymers) Section cross-reference(s): 51 Cyclohexyl bromide [108-85-0], C16-C24 alkyl bromides, dodecyl iodide [4292-19-7], 1-chloroeicosane [42217-02-7], dodecylbenzyl chloride [28061-21-4], and similar halides were used with ethylaluminum sesquichloride (I) [12075-68-2] as a catalyst for the oligomerization of 1-octene to prep. synthetic lubricating oils with high viscosity index, low pour point, and high oxidn. resistance. Thus, 10 g alkyl bromides (contg. 26% Br) prepd. by bromination of C16-C24 olefins were mixed with 96 mL 1-octene, and this soln. and a soln. prepd. from 106 mL 1-octene and 4 mL 25% I were added simultaneously during 30 min to a container at 120-5.degree. to prep. oligomers contg. C24 15.0, C32 21, C40 20.2, C48 16.6, and C56 and higher oligomers 10.4%.
