Table 24.5 shows the results obtained in treating a saturated solution of vacuum pan salt which would be more typical of that required for primary treatment in the chlor-alkali industry. Note that the higher feed concentration did not adversely affect the removal efficiency, even considering the higher hardness concentration. Complete hardness removal was obtained with 99% recovery of the NaCl values. 

Note It is estimated that in 1991, approximately 2 million kilograms of enzymes were consumed by the chemical and food production industries. Note included in the foregoing figures are enzymes for leather-bating, papain, peclinase, bromelain, and several others.

CIN (Chemical Industry Notes) is a bibliographic database covering worldwide business events in the chemical industry. It is produced by the American Chemical Society and covers 1974 to date. 

I ve broken out the data to show just chemical engineers, as this is the principal discipline in the science and engineering fields that moves into the chemical industry. Note that the slowdown in the production of engineers in the early 1990s in response to the declining economic conditions of those years is in a full-swing reversal. 

One participant, a representative from the energy industry, noted that there is a tremendous amount of worry and a sense of there being problems in the world related to oil in the Middle East and personal security. [The potential for hydrogen to help] reduce tensions and ameliorate foreign policy problems could benefit people s sense of well being. ... 

The potential value of hydrogen is difficult to explain to the public, because it is not something found in the ground, and it can be produced and used in many different ways. One representative of the energy industry noted We have branding issues. Hydrogen means different things to different people. ...

Summary 5-Aminotetrazole is prepared by reacting hydrazine monohydrate with hydrochloric acid, and calcium cyanamide solution. Afterwards, hydrochloric acid and sodium hydroxide are added, and then the mixture is heated. Afterwards, the mixture is cooled, and upon cooling, the 5-aminotetrazole precipitates. It is then collected by vacuum filtration.

Summary TAEN is prepared by reacting triazoethanol with a nitrating acid mixture. During the formation of the TAEN, the liquid product will condense forming an upper liquid layer. After the reaction, this upper layer is simply decanted, washed, and then dried over anhydrous sodium sulfate. Commercial Industrial note For related, or similar information, see Serial No. 

Summary DNAT, l,l -dinitro-3,3 -azo-1,2,4-triazole, is prepared by oxidizing 3-amino-1,2,4-triazole to 3,3 -azo-1,2,4-triazole with potassium permanganate, and then treating that intermediate with nitric acid in the presence of acetic anhydride. The precipitated product is then recovered by filtration, and then recrystallized from acetone.
