Relationships similar to those described for chloroform, water, and acetic acid are also found in the case of a number of other trios, e.g. ether, water, and alcohol chloroform, water, and alcohol They have also been observed in the case of a considerable number of molten metals. Thus, molten lead and silver, as well as molten zinc and silver, mix in all proportions but molten lead and zinc are only partially miscible with each other. When melted together, therefore, the...

Other mixtures which may be employed are carbon tetrachloride (b.p. 77°) and toluene (b.p. 110-111°) chloroform (b.p. 61°) and toluene methyl alcohol (b.p. 65°) and water (b.p. 100°). The last example is of interest because almost pure methyl alcohol may be isolated no constant boiling point mixture (or azeotropic mixture) is formed (compare ethyl alcohol and water, Sections 1,4 and 1,5). Attention is directed to the poisonous character of methyl alcohol the vapour should therefore not be inhaled. 

Methylene iodide [75-11-6], CH2I2, also known as diio dome thane, mol wt 267.87, 94.76% I, mp 6.0°C, and bp 181°C, is a very heavy colorless Hquid. It has a density of 3.325 g/mL at 20°C and a refractive index of 1.7538 at 4°C. It darkens in contact with air, moisture, and light. Its solubiHty in water is 1.42 g/100 g H2O at 20°C it is soluble in alcohol, chloroform, ben2ene, and ether. Methylene iodide is prepared by reaction of sodium arsenite and iodoform with sodium hydroxide reaction of iodine, sodium ethoxide, and hydroiodic acid on iodoform the oxidation of iodoacetic acid with potassium persulfate and by reaction of potassium iodide and methylene chloride (124,125). Diiodoform is used for determining the density and refractive index of minerals. It is also used as a starting material in the manufacture of x-ray contrast media and other synthetic pharmaceuticals (qv). 

AHyl chloride is a colorless Hquid with a disagreeable, pungent odor. Although miscible in typical compounds such as alcohol, chloroform, ether, acetone, benzene, carbon tetrachloride, heptane, toluene, and acetone, aHyl chloride is only slightly soluble in water (21—23). Other physical properties are given in Table 1. 

GHC13). It is readily soluble in alcohol, chloroform or benzene, less so in ther, and almost insoluble in cold water, but sparingly so in ammonia or me-water. Thebaine behaves as a monoacidic base. The hydrochloride,... 

Brucine crystallises from water or aqueous alcohol in monoclinic prisms containing 4H2O, m.p. 105° or 178° dry), [a]n — 119° to — 127° (CHCI3) or — 80-1° (EtOH). The alkaloid is slightly soluble in cold water fl in 320), more so in boiling water (1 in 150), very soluble in alcohol, chloroform, or amyl alcohol, sparingly soluble in ether (1 in 134). 

Valproic acid is slightly soluble in water. It is freely soluble in acetone, alcohol, chloroform, ether, benzene, n-heptane, methyl alcohol, and 0.1 N sodium hydroxide slightly soluble in 0.1 N hydrochloric acid [2,3],... 

Soluble in water, alcohols, chloroform, and ethyl acetate. It hydrolyzes to form Nivalenol.

Simple aliphatic carboxylic acids having upto four carbon atoms are miscible in water due to the formation of hydrogen bonds with water. The solubility decreases with increasing number of carbon atoms. Higher carboxylic acids are practically insoluble in water due to the increased hydrophobic interaction of hydrocarbon part. Benzoic acid, the simplest aromatic carboxylic acid is nearly insoluble in cold water. Carboxylic acids are also soluble in less polar organic solvents like benzene, ether, alcohol, chloroform, etc.
