Chloroformates methyl

Although less common, azeotropic mixtures are known which have higher boiling points than their components. These include water with most of the mineral acids (hydrofluoric, hydrochloric, hydrobromic, perchloric, nitric and sulfuric) and formic acid. Other examples are acetic acid-pyridine, acetone-chloroform, aniline-phenol, and chloroform-methyl acetate.

In like manner lodal (VI), on condensation with 6-nitro-3 4-methylene-dioxyphthalide (IV) yields nitro-a -adlumine (I R = NOj . O. CHa. O. at C and C replaced by 20Me), which crystallises from chloroform-methyl alcohol in orange, rectangular plates, m.p. 180-1° dec.), and on reduction yields the corresponding amino-derivative, bundles of minute needles, m.p. 218-9°.

Mg ribbon and fine Mg shavings can be ignited at air temps of about 950°F (Ref 26). Oxides of Be, Cd, Hg, Mo and Zn can react explosively with Mg when heated (Ref 8). Mg reacts with incandescence when heated with the cyanides of Cd, Co, Cu,Pb, Ni or Zn or with Ca carbide (Ref 9). It is spontaneously flam-mable when exposed to moist chlorine (Ref 10), and on contact with chloroform, methyl chloride (or mixts of both), an expl occurs (Ref 4). Mg also reacts violently with chlorinated hydrocarbons, nitrogen tetroxide and A1 chloride (Ref 14). The reduction of heated cupric oxide by admixed Mg is accompanied by incandescence and an expin (Ref 7).Mg exposed to moist fluorine is spontaneously flammable (Ref 11). When a mixt of Mg and Ca carbonate is heated in a current of hydrogen, a violent ex pin occurs (Ref 12). When Mo trioxide is heated with molten Mg, a violent detonation occurs (Ref 1). Liq oxygen (LOX) gives a detonable mixt when... 

The infrared region of the electromagnetic spectrum lies between the wavelengths 1000 and 15000 nm (Kemp AVellacdo, 1980). Absorption of radiation in this region by organic compounds has been known since 1866, when Tyndall first conducted experiments on the interaction of radiation with compounds such as chloroform, methyl and ethyl iodides, benzene.

Most structural work on xylan has been done on that from esparto grass and the principal attack made by way of the methyl ether. Xylan can be methylated by heating with methyl iodide and silver oxide,92-93 but complete etherification is difficult and considerable degradation probably occurs. On the other hand, complete etherification is attained by methylation in two operations with potassium hydroxide and dimethyl sulfate to give a dimethylxylan in almost quantitative yield70 showing [< ]22d — 92° in chloroform. Methylation with potassium hydroxide appears to proceed more readily than with sodium hydroxide.70-92...

Choudhury et al. [86] have studied the effect of polymer-solvent and clay-solvent interaction on the mechanical properties of the HNBR/sepiolite nanocomposites. They chose nine different sets of solvent composition and found that chloroform/methyl ethyl ketone (Qi/MEK) (i.e., HNBR dissolved in Ch and sepio-lite dissolved in MEK) is the best solvent combination for improvement in mechanical properties. XRD, AFM, , and UV-vis spectroscopy studies show that the dispersion of clay is best in the Ch/MEK solvent combination and hence polymer-filler interaction is also the highest. images shown in Fig. 14a, b clearly elucidate the aforementioned phenomena. Consequently, the tensile strength and modulus are found to be higher (5.89 MPa and 1.50 MPa, respectively) for the Ch/MEK system due to the minimum difference in interaction parameter of HNBR-solvent (xab) and sepiolite-solvent (Xcd)- Choudhury et al. have also studied the effect of different nanoclays [NA, , 15A, and sepiolite (SP)] and nanosilica (Aerosil 300) on the mechanical properties of HNBR [36].

The product from Step 5 (Immol) and cytosine (Immol) were dissolved in acetonitrile (25mmol), hexamethyldisilazane (Immol) and chlorotrimethylsilane (4mmol) added, and the mixture stirred at ambient temperature 30 minutes. The solution was cooled to -78 °C, trimethylsilyltrifluoromethane sulfonate (1.2 mmol) added, and the solution stirred 2.5 hours. Thereafter, the mixture was warmed to ambient temperature, concentrated to 5 ml, diluted with 50 ml CH2CI2, washed with 20 ml water, dried, and concentrated. The residue was purified by chromatography over silica gel using chloroform/methyl alcohol, 98 2, and the product isolated in 77.5% yield. H-NMR, elemental analysis, and MS data supplied. 

Stirred 2 hours at 0°C, solid bis(phenylsulfonyl) sulfide (2.21 mmol) added, the reaction cooled to -78 °C, and then stirred 3 hours. Thereafter, the reaction mixture warmed to ambient temperature and stirred overnight. The mixture was extracted 3 times with 100 ml water, dried, and concentrated. It was purified by chromatography as described in Step 1 and re-crystallized in chloroform/methyl alcohol. The product was isolated in 65% yield as a white solid, mp = 153.5-154°C. H- and C-NMR and MS data provided. 

Solubility ethylcellulose is practically insoluble in glycerin, propylene glycol, and water. Ethylcellulose that contains less than 46.5% of ethoxyl groups is freely soluble in chloroform, methyl acetate, and tetrahydrofuran, and in mixtures of aromatic hydrocarbons with ethanol (95%). Ethylcellulose that contains not less than 46.5% of ethoxyl groups is freely soluble in chloroform, ethanol (95%), ethyl acetate, methanol, and toluene.
