Uses ndReactions. Dihydromyrcene is used primarily for manufacture of dihydromyrcenol (25), but there are no known uses for the pseudocitroneUene. Dihydromyrcene can be catalyticaUy hydrated to dihydromyrcenol by a variety of methods (103). Reaction takes place at the more reactive tri-substituted double bond. Reaction of dihydromyrcene with formic acid gives a mixture of the alcohol and the formate ester and hydrolysis of the mixture with base yields dihydromyrcenol (104). The mixture of the alcohol and its formate ester is also a commercially avaUable product known as Dimyrcetol. Sulfuric acid is reported to have advantages over formic acid and hydrogen chloride in that it is less compUcated and gives a higher yield of dihydromyrcenol (105).

A slow non-competing liquid/liquid reaction with no catalyst present gave only 78 % O-alkylation. Thus the active site of the lipophilic phosphonium ion catalysts appears to be aprotic, just as in analogous phase transfer catalyzed alkylations with soluble quaternary ammonium salts 60), Regen 78) argued that the onium ion sites of both the 17% and the 52% RS tri-n-butylphosphonium ion catalysts 1 are hydrated, on the basis of measurements of water contents of the resins in chloride form. Mon-tanari has reported measurements that showed only 3.0-3.8 mols of water per chloride ion in similar 25 % RS catalysts 74). He argued that such small hydration levels do not constitute an aqueous environment for the displacement reactions. No measurements of the water content of catalysts containing phenoxide or 2-naphthoxide ions have been reported. 

Five to ten grams of tris (ethylenediamine) chromium (III) chloride SU-hydrate are spread in a thin even layer on an open Petri dish embedded in a sand bath that carries a thermometer. The bath is maintained at 210°C until the product lias lost at least 25% of its original weight (theory = 80.6%). The evolution of amine soon begins and the yellow salt slowly darkens over a period of an hour or two, finally yielding a red-violet material. 

Anhydrous ruthenium(lll) chloride, RuCL, is made by direct chlorination of the metal at 700°C. Two aliotropic forms result. The trihydrate is made by evaporating an HQ solution of rulheinuiu(III) hydroxide to dryness or reducing ruthenium(VIII) oxide in a HQ solution. The tnhydrate, RuCk 3R>0, is the usual commercial form. Aqueous solutions of the tri-hydrate are a straw color in dilute solution and red-brown in concentrated solution. Ruthenium(lll) chloride in solution apparently forms a variety of aquo- and hydroxy complexes. The analogous bromide. RuBr3, is made by the same solution techniques as the chloride, using HBr instead of HQ. 

Three grams of tris(biguanidato)chromium(III) 1-hydrate is triturated in a mortar with 3 N hydrochloric acid in the cold (10°) until the mixture gives a slight acid reaction (8 ml. of acid is required). The red 1-hydrate is converted completely into yellow crystals of the hydrochloride which are filtered and washed with 3 to 5 ml. of cold water. The crystals are purified by recrystallizing from 38 ml. of water, filtering, and washing, first with 3 ml. of ice-cold water and then with 5 ml. of alcohol. The mother liquor is treated with a saturated solution of ammonium chloride to complete precipitation, and the second crop of crystals is treated as the first. The total yield is 2.45 g. (0.0053 mol or 66%). 

Hydrated tris(phenylbiguanide)cobalt(III) chloride forms needle-shaped, red crystals which are soluble in water and alcohol but insoluble in ether and acetone. When heated to 110° for 15 hours, the hydrate loses the whole of its water to form the red anhydrous salt. The solution of the complex chloride gives colored precipitates with a number of complex anions such as hexacyanoferrate(II), hexacyano-ferrate(III), nitroprusside, hexacyanocobaltate(III), and chloroplatinate. 

Five grams of nickel(II) chloride 6-hydrate and 12.1 g. of tris(ethylenediamine)nickel(II) chloride 2-hydrate J are gently refluxed for 5 minutes with a mixture of 47.5 ml. of methanol and 2.5 ml. of water, shaking at first until all the salts are dissolved. A beautiful deep blue solution results. This is filtered by gravity while still warm into a 400-ml. beaker, and the flask and paper are washed once with 5 ml. of hot methanol. Seed crystals are obtained by adding 3 to 4 ml. of acetone slowly to 2 to 3 ml. of the blue solution and scratching or shaking until crystals form the separation of two liquid phases indicates the addition of too much acetone and makes the formation of crystals difficult.

For the preparation of tris(ethylenediamine)nickel(II) chloride 2-hydrate, 28 g. of 70% aqueous ethylenediamine is added to a solution of 23.8 g. (0.1 mol) of NiCl2 6H20 in 100 to 150 ml. of water. The purple solution is filtered to remove the small amount of hydrous iron oxide which precipitates and is then evaporated to a volume of 60 to 70 ml. on a steam bath. Two drops of ethylenediamine are added, and the solution is cooled in an ice bath. The orchid-colored crystals that form are collected by suction, washed twice with 95 % ethanol, and air-dried. The yield is 28.6 g. (80%). Several more grams may be recovered from the mother liquor by adding ethanol and cooling. Anal. Calcd. for [Ni(C2H8N2)3]Cl2-2H20 Ni, 16.97% Cl, 20.50%.
