Gas-phase adsorption can also be used when regenerating the adsorbent is not practical. Most of these appHcations are used where the faciHties to effect a regeneration are not justified by the small amount of adsorbent in a single unit. Nonregenerative adsorbents are used in packaging, dual-pane windows, odor removal, and toxic chemical protection. 

Additional uses iaclude (/) filling the enclosed space ia double-pane wiadow units to reduce noise and heat transmission (87,88) (2) acting as a source of power from the reaction with lithium to produce heat (89,90) and (J) pressurizing recreation ball packages such as tennis balls to give improved shelfhfe (91). 

Another nonregenerative drying appHcation for molecular sieves is their use as an adsorbent for water and solvent in dual-pane insulated glass windows. The molecular sieve is loaded into the spacer frame used to separate the panes. Once the window has been sealed, low hydrocarbon and water dew points are maintained within the enclosed space for the lifetime of the unit. Consequently, no condensation or fogging occurs within this space to cloud the window.

Sihcate glass is a familiar, ubiquitous material, used in beverage containers, window panes, and automobile windshields. Increasingly, however, unusual glasses are being employed in high technology appHcations. 

Because the system likely is nonisothermal, the analysis of a closed-desiccant system requites knowledge of the temperature of the desiccant as well as the dew point (ice point) or water concentration (partial pressure) specification. Indeed, the whole system may undergo periodic temperature transients that may compHcate the analysis. Eor example, in dual-pane windows the desiccant temperature is approximately the average of the indoor and outdoor temperatures after a night of cooling. However, after a day in the sun, the desiccant temperature becomes much warmer than the outdoor temperature. When the sun sets, the outdoor pane cools quickly while the desiccant is still quite warm. The appropriate desiccant for such an appHcation must have sufficient water capacity and produce satisfactory dew points at the highest temperatures experienced by the desiccant. 

In cold climates, many homes and businesses use double and triple pane tows. The air pocket between double and triple pane windows serves to insulate so that heat is not lost through the windows. Likewise, air bubbles in oil prevent the heat from escaping.

Hence it must be either trans- or c 5-l-cyclopropyl-2-methylbuta-1,3-diene (1-isoprenylcyclopro-pane), G or H. 

The rates of brominolysis of a series of 1,2-diarylcyclopropanes under conditions where the rate is determined by Br- attack and leads to l,3-dibromo-l,3-diarylpro-panes are given below. 

Another original approach is exemplified by Ciba-Geigy s XU292. BMI is mixed with o,o -diallylbisphenol A (DAP, 2,2-bis(3-allyl-4-hydroxyphenyl)pro-pane Fig. 9) followed by heating to 110-125°C to obtain a liquid pre-polymer. The pre-polymer could be cured in the same way as common maleimide and epoxy resins are done [ 16,17]. 

For single glazing, the determination of the absorbed and transmitted radiation and of the heat transfer is quite straightforward, but for a window with multipane glazing, the calculation is more complex. Besides conduction in the panes, convection in the gaps as well as multiple reflections between the individual panes must be considered. 

For the calculation of such glazing in building-dynamics simulation codes, each pane is considered as a layer, exchanging energy with the other panes, with the room, and with the exterior. 

For each layer the energy conservation equation is solved. The individual terms are the absorbed radiation in the layer and the radiative and convective heat exchange to the adjacent panes, to the room, or to the exterior.

Instead of calculation of overpressure and impulse at a flxed distance, the distance at which damage can occur will be calculated. The speciflc type of damage chosen is window pane breakage. This can be expected at overpressures greater than 6 kPa (0.06 bar).
