The IFP Dimersol Process for dimerization of propylene into isohexenes

The IFP Dimersol Process for dimerization of propylene into isohexenes. An attractive alternate to propylene alkylation. Andrews, John; Bonnifay, Pierre (Inst. Fr. Pet., New York, N. Y., USA). ACS Symp. Ser., 55(Ind. Lab. Alkylations), 328-40 (English) 1977. CODEN: ACSMC8. DOCUMENT TYPE: Journal CA Section: 51 (Fossil Fuels, Derivatives, and Related Products) Section cross-reference(s): 23 In the title process, dried feedstock is dimerized at ambient temp. and under sufficient pressure to maintain a liq. phase in the presence of low concns. of sol. catalysts. The reactor effluent is neutralized, washed, and isohexene [27236-46-0] is sepd. from liquefied C3 hydrocarbons in a depropanizer. The properties of the dimers, such as research octane no. 97, are compared with those of C3 alkylate.

Heterogeneous, nickel-containing catalysts

Heterogeneous, nickel-containing catalysts. Yoo, Jin Sun (Atlantic Richfield Co., USA). U.Several substances are used for example 61526-19-0 and 115-11-7 which are their cas registry numbers.S. US 3992470 16 Nov 1976, 9 pp. Division of U.S. 3,907,923. (English). (United States of America). CODEN: USXXAM. CLASS: IC: C07C. NCL: 260680000B. APPLICATION: US 70-49968 25 Jun 1970. DOCUMENT TYPE: Patent CA Section: 35 (Synthetic High Polymers) Bis(triphenylphosphine) nickel dicarbonyl (I) [13007-90-4] supported on an acidic, calcined, alumina-silica support contg. a sep. alumina phase was used as a catalyst in the oligomerizaton, esp. dimerization, of ethylene and propylene, the codimerization of a conjugated diene and an .alpha.-olefin, and the polymn. of conjugated dienes. Thus, 10 g calcined alumina-silica extrudate pellets were added to a homogeneous soln. of 0.98 mmole I in 32 ml. toluene to give brown pellets after 1.5 h. The liq. phase was removed, and the pellets were washed several times with toluene. Propylene (67.6g) was fed to the catalyst in a 300 ml. stainless steel autoclave with an air driven stirrer and heated 70 min at 140-160.degree.F while the pressure dropped from 240 to 100 psig. The resulting clear reaction mixt. comprised 2,3-dimethylbutene [27416-06-4] 15, 2-methylpentene [27236-46-0] 53, hexene [25264-93-1] 16, and high-boiling products (mostly C9-olefins) 15%. The overall conversion of the propylene feed was 87%. .
