Coal liquefaction by the hydrogen produced from methanol: Coal liquefaction by the hydrogen produced from methanol. 2. Model compound studies. Mondragon, Fanor; Kamoshita, Ryuji; Katoh, Takashi; Itoh, Hironori; Ouchi, Koji (Fac. Eng., Hokkaido Univ., Sapporo 060, Japan). Fuel, 63(5), 579-85 (English) 1984. CODEN: FUELAC. ISSN: 0016-2361. DOCUMENT TYPE: Journal CA Section: 51 (Fossil Fuels, Derivatives, and Related Products) Coal can be converted into a material sol. in solvents using MeOH [67-56-1] as an in-situ H source and also as an alkylating agent. This paper presents the results of the reaction of selected model compds. with MeOH using 2 different hydrogenation catalysts: stabilized Ni at 365°, and stabilized Co at 405° and 445°. Stabilized Ni is a much better hydrogenation catalyst than is stabilized Co. Alkylation is strongly dependent on the presence of specific functional groups (e.g., -OH, -NH). Also, alkylation is independent of the hydrogenation catalyst used and seems to depend more on the temp. The alkylated products from the reactions at 405° showed an order as follows: carbazole [86-74-8] > PhOH [108-95-2] >> phenanthrene [85-01-8] > dibenzofuran [132-64-9] > Ph2O [101-84-8] > dibenzothiophene [132-65-0] > Ph2CH2 [101-81-5]. A free radical mechanism is proposed for the alkylation reaction.

DOCUMENT TYPE: Journal CA Section: 51 (Fossil Fuels, Derivatives, and Related Products) Section cross-reference(s): 25 The redn. of Ph2CO [119-61-9] by H-donor mols. such as Tetralin [119-64-2] and dihydroanthracene [613-31-0] to give Ph2CH2 [101-81-5] was examd. at 300-400°. The reaction occurs in 3 stages. The first is a radical process which gives Ph2CHOH [91-01-0]. In the second, Ph2CHOH undergoes an SN reaction to produce water and bis(diphenylmethyl) ether (I) [574-42-5]. I disproportionates in a readily initiated free-radical chain reaction to give Ph2CH2 and Ph2CO. .
