Summary HNS is prepared by reacting TNT with sodium benzoate in the presence of DMSO (dimethylsulfoxide). The reaction is carried out in the presence of dry excess oxygen to ensure quality. After the reaction mixture has been stirred for some time, the mixture is treated with cold water to precipitate the crude HNS. The cmde HNS is then washed with methanol and acetone to dissolve impurities. Commercial Industrial Note Part or parts of this laboratory process may be protected by international, and/or commercial/industrial processes. Before using this process to legally manufacture the mentioned explosive, with intent to sell, consult any protected commercial or industrial processes related to, similar to, or additional to, the process discussed in this procedure. This process may be used to legally prepare the mentioned explosive for laboratory, educational, or research purposes. 

Butter should be stored at 4.4°C or lower or at less than — 17.8°C, if it is to be held for more than 30 days (62). The International Dairy Federation (IDF) has produced specifications for milkfat (64), which include reference to the feedstock. (These specifications relate to the time of manufacture but are often used as purchase standards.) The highest grade, anhydrous milkfat (AMF), must be produced from fresh milk, cream, or butter, to which no neutralizing substances have been added. It should have a clean, bland flavor when tasted at 20-25°C and a peroxide value (PV) of less than 0.2 meq oxygen/1 kg fat. Anhydrous butter oil may be produced from butter or cream of different ages and has no pronounced, unclean, or other objectionable taste or flavor. The term butter oil should be used where there is no pronounced unclean or other objectionable taste or odor. The FAOAVHO Codex standard for milkfat is shown in Table 15 (65). 

In July 1962 a Workshop on Oxygen Administration under Increased Atmospheric Pressure was held in Washington, D.C., under the auspices of the National Research Coimcil (Al). There have been numerous s3on-posia pertaining to high pressure oxygen therapy on local, regional, national, and international levels. Industries that never before manufactured pressure chambers suddenly became involved in this venture some have dropped...
