| SOLUBILITY | Insoluble in Water and Alcohol. Soluble in Chloroform, Solvent Ether and Light Petroleum (boiling range 40° C to 60° C). The solutions sometimes showing a slight opalescence. |
| STANDARDS | White Soft Paraffin is a purified mixture of semisolid hydrocar-bons obtained from Petroleum and Bleached. |
| MELTING RANGE | Between 42° C to 47° C |
| LIGHT ABSORPTION | < 0.5 (Extinction of a 1 Cm. layer of a 0.05% w/v solution in is octane at 290 mm.) |
| FIXED OILS, FATS AND ROSIN | Passes (Digest 10 g with 50 ml of Sodium Hydroxide solution at 100° C for thirty minutes and allow the aqueous layer to separate on acidifying the aqueous layer with dilute Sulphuric Acid no precipitate of oily matter is observed ) |
| ACIDITY OR ALKALINITY | Passes (Boil 5 g with 10 ml of alcohol previously neutralized to litmus solution the suspension is neutral to litmus solution.) |
| FOREIGN ORGANIC MATTER | Passes (Volatilises when heated without emitting an acid odor) |
| SULPHATED ASH | < 0.1% (Weight accurately about 0.3 g and gently boil with 150 ml of Water and 100 ml of Sodium Hydroxide solution for six hours in an ammonia distillating apparatus collecting and distillate in 40 ml of a 4.0% w/v solution of boric acid. Increase the temperature and distile about 200 ml cool add 75 ml of water distil a further 70 ml into the same receive and titrate with 0.1 N hydrochloric acid using methyl red solution as indicator. Repeat the operation without the substance being examined the difference between the titrations represent the acid require to neutralize the Methylamine formed from the Paramethadione each ml of 0.1 N hydrochloric acid is equivalent to 0.01572 g of CH11 NO3) |
