To 1,400 ml of an approximately 50% water/triglycol solution of the potassium salt of cheno-deoxycholic acid, obtained by the Wolff-Kishner reduction (using hydrazine hydrate and potassium hydroxide) from 50 g of 7-acetyl-12-ketochenodeoxycholic acid, 220 ml of dilute hydrochloric acid is added to bring the pH to 2. The solution is stirred and the crude cheno-deoxycholic acid precipitates. The precipitate is recovered and dried to constant weight at about 60°C. About 36 g of the crude chenodeoxycholic acid, melting in the range of 126°-129°C, is obtained.

Glycol, diglycol and triglycol are at present used for manufacturing their nilric esters all over the world. Glycol dinitrate, or nitroglycol, is the most important...

For a 500 kg charge of triglycol, 1250 kg of nitrating acid were used, nitration being carried out during a period of 30 min. 

The solubility of dinitrotriethylene glycol in the spent acid is exceptionally high amounting to 8-9%. Denitrating such an acid can be hazardous in view of the presence of such a large amount of an explosive substance. Separation takes place slowly and lasts over half an hour. This is an added hazard, since dinitro-triglycol readily decomposes in the presence of spent add. It is therefore necessary to add water to the spent acid before the oily explosive material is separated, and the residual spent acid is transferred to the denitration unit. The separated oil is washed twice with water, then with a sodium carbonate solution and finally with water. A sample of washed and neutralized triethylene glycol dinitrate should withstand the heat test for 20 min at 82°C. 

Macrocyclic diamine 14 and triglycolic acid dichloride 15 were condensed under high-dilution conditions to form 16 in 45 % yield. Subsequent reduction of 16 using diborane yielded the [2.2.2]cryptand as the bis-borane adduct. Acidic work-up with 6 N hydrochloric acid afforded 7 in 90% yield. 

Diglycol dinitrate was used extensively in the Second World War by the German side as one of the main components of -> Double Base Propellants. The explosion heat of diglycol in powder form can be kept lower than the heats of the corresponding nitroglycerine powders they represented the first step towards the so-called cold powders. Diglycol dinitrate and triglycol dinitrate are also employed as rocket propellants. 

A number of liquid nitrate esters other than nitrocellulose have been recently used, including diglycol dinitrate, metriol trinitrate, and butane-triol trinitrate, of which diglycol dinitrate has been the most extensively employed. Powders prepared with it or with triglycol dinitrate are lower in calories. This fact is relevant to the service life of the gunbarrels in which these powders are utilized. Such powders are known as cold propellants . 

Triglycol dinitrate is less volatile than - Diethylenglycol Dinitrate. It gelatinizes nitrocellulose just as well as diglycol dinitrate, i.e., better than nitroglycerine. 

Triglycol dinitrate is prepared by nitration of triglycol with mixed acid. The solubility of triglycol dinitrate in the waste acid is very high ( 9 %). It is less volatile than -> Diethyleneglycol Dinitrate. It is particularly suited for the production of low caloric -> Double Base Propellants.
