The inflammable solvents most frequently used for reaction media, extraction or recrystallisation are diethyl ether, petroleum ether (b.p. 40-60° and higher ranges), carbon disulphide, acetone, methyl and ethyl alcohols, di-Mo-propyl ether, benzene, and toluene. Special precautions must be taken in handling these (and other equivalent) solvents if the danger of Are is to be more or less completely eliminated. It is advisable to have, if possible, a special bench in the laboratory devoted entirely to the recovery or distillation of these solvents no flames are permitted on this bench. 

Compounds which dissolve in concentrated sulphuric acid may be further subdivided into those which are soluble in syrupy phosphoric acid (A) and those which are insoluble in this solvent (B) in general, dissolution takes place without the production of appreciable heat or colour. Those in class A include alcohols, esters, aldehydes, methyl ketones and cyclic ketones provided that they contain less than nine carbon atoms. The solubility limit is somewhat lower than this for ethers thus re-propyl ether dissolves in 85 per cent, phosphoric acid but re-butyl ether and anisole do not. Ethyl benzoate and ethyl malonate are insoluble. 

When exposed to ait, the sodium salts tend to take up moisture and form dihydrates. The alkah metal xanthates are soluble ia water, alcohols, the lower ketones, pyridine, and acetonitrile. They are not particularly soluble ia nonpolar solvents, eg, ether or ligroin. The solubiUties of a number of these salts are Hsted ia Table 4. Potassium isopropyl xanthate is soluble ia acetone to ca 6 wt %, whereas the corresponding methyl, ethyl, / -propyl, n-huty isobutyl, isoamyl, and benzyl [2720-79-8] xanthates are soluble to more than 10 wt % (12). The solubiUties of the commercially available xanthates ia water are plotted versus temperature ia Figure 1 (14).

Addition of alcohol to alkenes hy alkoxymercuration-reduction produces ethers via Markovnikov addition. This addition is similar to the acid-catalysed addition of an alcohol. For example, propene reacts with mercuric acetate in aqueous THF, followed hy reduction with NaBFl4, to yield methyl propyl ether. The second step is known as demercuration, where Flg(OAc) is removed hy NaBH4. Therefore, this reaction is also called alkoxymercura-tion-demercuration. The reaction mechanism is exactly the same as the oxymercuration-reduction of alkenes. 

The solubility of potassium chloride in ethyl alcohol of sp. gr. 0"939 rises from 4-0 at 0° to 118 at 60°. Similar results are obtained with other mixtures of alcohol and water. According to C. A. L. de Bruyn,32 100 grms. of 98 per cent, methyl alcohol dissolve T22 grms. of sodium chloride, and 14 grms. dissolve in 40 per cent, methyl alcohol 100 grms. of propyl alcohol of sp. gr. 0"816 dissolve 0033 grm. of sodium chloride at room temp., while potassium chloride is almost insoluble in this menstruum, and luminescence occurs when soln. of hydrogen chloride in propyl alcohol are treated with potash lye.33 At 17°, 100 mols. of acetic ether dissolve 0"31 mol. of sodium chloride, and at 40°, 0-037 mol. 

Ethers methyl, ethyl, propyl, butyl etc. ethers in mixtures with alcohols. 

Mixed ethers result when alcohols and phenols are used with thoria at 390°—420° and esterification takes place when alcohol and acid interact at 350°-400°. Esterification10 is more complete in the presence of titanic oxide at 280°—300°. One molecule of acid is used with twelve molecules of alcohol, and in this way methyl, ethyl, propyl, butyl, and benzyl esters have been prepared from acetic, propionic and butyric acids. 

Acetic anhydride (10.96 mmol) was added to l-(4-fluorophcnyl-3(//)-(3(.S )-hydroxy-3-(4-fluorophenyl)propyl))-4(5)-(4-hydroxyphenyl)-2-azetidinone (4.98 mmol) containing dimethylaminopyridine (11.96 mmol) dissolved in 15 ml THF and the reaction monitored by TLC using 5% methyl alcohol/toluene. Thereafter, the mixture was then diluted with diethyl ether, washed with 1M HC1 and brine, and dried using Na2S04. The solution was concentrated and the product isolated in 100% yield and used without additional purification.

Lead n-propyl isoamyl dichloride is obtained from lead methyl n-propyl isoamyl chloride, and crystallises from hot alcohol, in which it is easily soluble, in plates, insoluble in benzene, ether, ethyl acetate, or water. The mlphide may be obtained in the usual way, and it is readily soluble in alcoliolic ammonium sulphide, sparingly in aqueous ammonium sulphide.
