Generators, types

There are some alternatives to this HCI generator type of crystallization. There are, of course, canisters of HCI gas that can be purchased. Also, one can crystallize with very concentrated (fuming) HCI by pouring the stuff directly into the ether/freebase [26]. Regular 35% HCI can do this too, but the water content may dissolve the MDA.HCl or make the crystals sticky which means that the chemist will have to dry the solution by removing the water. 

Synchronous generator type is in use for all generating applications up to the highest ratings (660 MW and above). The machine is operated at synchronous speed and the terminal voltage and power factors of operation are controlled by the excitation.

There are two main classes of SCBA the closed circuit, or recirculating, and the open circuit. The former is more expensive to purchase but less expensive to operate, particularly if using oxygen. There are two types of the closed circuit class the oxygen generating type and the compressed gas (oxygen or air) type. 

Fig. 13. The effect of the minimum ionic strength, / , on the pH-rate profile for a typical enzymatic reaction. Two types of curves are generated Type I, bell shaped type II, monotonically decreasing, depending on the pH of the experiment. Graphing the pH behavior as a function of ionic strength (a and b show the transformation) and applying the / cut-off (c), it can be seen that, if experimental pH at is lower than the pH optimum, a type I curve is obtained. If the experimental pH is greater, a type II is obtained.

Chemical Pots or Smoke Pots Portable containers, usually cylindrical in shape, filled with a chemical smoke-producing agent. They may be subdivided into "burning and "generator types. The former type is usually filled with a mixt consisting of HC 47, ZnO 47 granulated A1 6% when ignited it burns with evoln of dense smoke.

Ozone was prepared with an ozone generator (type OZ II of the Fischer Labortechnik, Bad Godesberg, Germany). Dry oxygen containing about 10% ozone was introduced at a speed of 10-20 liters/hour in the olefin solution at —78°C. Dry and olefin-free n-pentane was used as solvent. 

An interesting route to generate type I aziridines which is formally the formation of bond b is shown in Equation (5) <2002BML3141>. Oxime 21 is prepared in high yield from the corresponding tetralone. Reduction of oxime 21 with LiAlH4 and diethylamine in tetrahydrofuran (THE) provides the unprotected type I aziridine 22 in good yield. 

Neuropeptide Y. Neuropeptide Y (NPY) is a 36 amino acid polypeptide that is involved in hormonal, sexual, and cardiac effects (232, 233). In 1994, two "first generation" type I NY-1 selective antagonists, BIBP 3226 (129) (234) and SR120107A (130)(235) were reported (Fig. 15.53). BIBP 3236 (129) corresponds to a truncated and modified peptide in which the D-Arg is assumed to correspond with Arg in Neuropeptide Y.
