CS2, inside

A mixture of steam, CS2 and air with a temperature of approximatly 95 °C is sucked off from the CS2-box. Most of the vapour is condensed in the vapour condenser by mixing with water. The water temperature at the outlet of the condenser is approximately 70 to 75 °C, and the same water flows back into the acid water circulation system, to compensate for the water carried out of the system by the product. The feed temperature of the water to the vapour condenser should not be lower than 50 °C to avoid condensation of CS2 inside the vapour condenser. 

Fenian Fire (Feu liquide in Fr). Incendiary compn consisting of a soln of yellow phosphorus in CS.J After evapn of the solv, phosphorus catches fire and ignites the surrounding flammable materials. Darapski proposed charging incendiary projectiles with the soln consisting of yellow phosphorus (3p) and CS2 (1.3p). Inside this soln was placed a leather bag contg petr oil with other combustible materials Ref Daniel (1902), 153... 

More recently, a chemical map of gadolinium atoms in metallofullerene molecules (Gd Cs2), themselves inside a single-wall carbon nanotube was obtained. Individual Gd atoms could be detected [17], Nanotubes [18, 19] and spheres [20, 21] were also studied, introducing anisotropy and relativistic effects in the simulation of LELS. The agreement is particularly...

Kikuchi et al. (1994c) showed that the endohedral form of metallofullerenes was not affected by the recoil energy of the metal atom resulting from the emission of electrons in the S-decay in which nuclear reaction and decay processes are related to Ga Cg2, Tb C82, and Gd Cs2-Successful encapsulation of radioactive atoms inside the fullerene cage will widen the potential use of metallofullerenes not only in materials science and technology but in biological and even medical science. 

Fullerenes with only one metal atom inside - mono-metallofullerenes. All rare earth metals can form mono-metallofullerenes. Although the carbon cages that can incorporate one metal atom range from Ceo to bigger than Cioo, as detected by mass spectrometry, the most extractable and stable species are exclusively M Cs2 normally, more than one cage isomer can be isolated. To date, only those mono-metallofullerenes with cages of C72 [32], C74 [33,34], and Cs2 [35] have been determined structurally. 

Fullerenes with two metal atoms inside - di-metallofuUerenes. M2 C2 type EMFs are also found for most rare earth metals, but the isolated examples are less than the corresponding mono-metallofullerenes. The most stable and extractable species are always M2 Cso [7] recently, M2 C2n (2n = 66, 72, 76, 78, 82, 84) [36-39] were also isolated and structurally characterized. Di-metallofullerenes with two different metals were also produced inside one cage, such as HoTm Cs2 [40], but its structure has not been determined yet. 

S) and its trans- and ciy-4a,7-H-7-ethyl derivatives indicated that trans-4a,7-H-7-ethylperhydropyrido[l,2-c][l,3]thiazine and the ds-4a,7-H-7-ethyl analog exist exclusively in the rrans-fused and the S-inside cis-fused conformation, respectively, containing the ethyl group in the equatorial positions, whereas the parent perhydropyrido[l,2-c][l,3]thiazine in CDCI3 at 25°C is a ca. 25 75 mixture of the S-inside c/s-fused and tra/u-fused conformations. At -75°C, where the interconversion is slow in a 1 1 mixture of CS2 and THF-dg, the signals of both conformers of perhydropyrido[l,2-c][l,3] thiazine can be detected. The NMR spectrum shows the presence of 64% of the frans-fused and 36% of the S-inside cis-fused conformer [82OMR(20)239].
