The importance of the thin film between the mineral particle and the air bubble has been discussed in a review by Pugh and Manev [74]. In this paper, modem studies of thin films via SFA and interferometry are discussed. These film effects come into play in the stability of foams and froths. Johansson and Pugh have studied the stability of a froth with particles. Small (30-/ m), moderately hydrophobic 6c = 65°) quartz particles stabilized a froth, while more hydrophobic particles destabilized it and larger particles had less influence [75].

Six protective groups for alcohols, which may be removed successively and selectively, have been listed by E.J. Corey (1972B). A hypothetical hexahydroxy compound with hydroxy groups 1 to 6 protected as (1) acetate, (2) 2,2,2-trichloroethyl carbonate, (3) benzyl ether, (4) dimethyl-t-butylsilyl ether, (5) 2-tetrahydropyranyl ether, and (6) methyl ether may be unmasked in that order by the reagents (1) KjCO, or NH, in CHjOH, (2) Zn in CHjOH or AcOH, (3) over Pd, (4) F", (5) wet acetic acid, and (6) BBrj. The groups may also be exposed to the same reagents in the order A 5, 2, 1, 3, 6. The (4-methoxyphenyl)methyl group (=MPM = p-methoxybenzyl, PMB) can be oxidized to a benzaldehyde derivative and thereby be removed at room temperature under neutral conditions (Y- Oikawa, 1982 R. Johansson, 1984 T. Fukuyama, 1985).

In 1984 in San Juanico (Mexico City), a 1600-m tank 50% full of LPG led to a BLEVE resulting in a fireball of 365 m in diameter (Johansson, 1986 Pietersen, 1985 Section 2.4.3). If it is assumed that all the fuel (468,000 kg) formed the fireball, the diameter calculated from the relationship proposed by Roberts (1982) and Jaggers et al. (1986) is 450 m. Assume, as proposed by Lihou and Maund (1982), that only 42% of the fuel originally in the tank contributes to the BLEVE. Then the calculated diameter using Roberts equation (6.2.16) is 337 m, a value in better agreement with witnesses estimates.
