Alkylation during supercritical dissolution of lignite in lower aliphatic alcohols: Alkylation during supercritical dissolution of lignite in lower aliphatic alcohols. Tegai, F.; Korniets, E. D.; Men'shov, V. I.; Rubailo, A. I.; Aliulin, V. V.; Plonskii, E. Ya.; Kirilets, V. M. (KATEKNIIugol, USSR). Khim. Tverd. Topl. (Moscow), (3), 80-4 (Russian) 1985. CODEN: KTVTBY. ISSN: 0023-1177. DOCUMENT TYPE: Journal CA Section: 51 (Fossil Fuels, Derivatives, and Related Products) The dissoln. of brown coal in MeOH [67-56-1], EtOH [64-17-5] or iso-PrOH [67-63-0] at supercrit. temp. and pressure not only dissolves the org. part of brown coal, but it also gives alkylation products resulting from the coal-alc. reactions. This was confirmed by heating PhOH [108-95-2] or m-cresol [108-39-4] (coal models) at 400° in an autoclave contg. C1-C3 alcs. The products included mono-Me to tri-Me-substituted phenols and also o-ethylphenol [90-00-6].

Upgrading of coal liquids by O-alkylation of phenols with olefins: Upgrading of coal liquids by O-alkylation of phenols with olefins. Part I. Reaction with branched olefins. Gould, Kenneth A.; Long, Robert B. (Corp. Res. Sci. Lab., Exxon Res. and Eng. Co. 513-35-9 and 106-44-5 are cas registry numbers. These chemicals are also mentioned in this article., Linden, NJ 07036, USA). Prepr. - Am. Chem. Soc., Div. Pet. Chem., 27(4), 916-26 (English) 1982. CODEN: ACPCAT. ISSN: 0569-3799. DOCUMENT TYPE: Journal CA Section: 51 (Fossil Fuels, Derivatives, and Related Products) Phenols in a coal naphtha (from donor-solvent liquefaction) were extd. by NaOH, sepd., neutralized, re-extd. with Et2O, and O-alkylated with 2-methyl-2-butene [513-35-9] in the presence of 40% H2SO4 in MeOH to give a 65% yield of aryl ethers. Ether formation is an equil. reaction favored by low temps. and short reaction times (e.g., room temp. and 4 h), is influenced by steric hindrance ortho to the hydroxyl group, and competes with ring alkylation, as detd. by alkylation of model compds. (i.e., p-cresol [106-44-5], 2,4-dimethylphenol [105-67-9], o-ethylphenol [90-00-6], and 2,6-dimethylphenol [576-26-1]). Phenols can be etherified in-situ in the naphtha without prior base extn. Coal liqs. contg. O-alkylated phenols are more stable than untreated coal liqs. .
