When infrared drying is used, the loss of active ingredients is even higher for some herbs as shown in Table 30.4 [23]. In this drying experiment, the IR radiates sideways toward the fixed bed of herb pieces. The depth of the bed is 30 mm. The initial mass of the wet material is about 400 g. It is interesting...

Radiant heat baking n. Curing treatment in which heat is transferred to the paint surface mainly by radiation from a hot surface, e.g., electric lamps or gas heated panels. This is also known as infrared drying or infrared baking. 

Many vibrational-rotational transitions of molecules such as H2O or CO2 fall within the range 3—10 xm, causing selective absorption of the transmitted radiation. Infrared spectrometers therefore have to be either evacuated or filled with dry nitrogen. Because dispersion and absorption are closely related, prism materials with low absorption losses also show low dispersion, resulting in a limited resolving power (see below).

After its application, the wet coat must be dried. Three different drying principles are used radiation (infrared), convection (hot air), and contact (cylinders). 

Special drying methods, such as superheated steam, solvent, vacuum, infrared radiation, and high frequency dielectric and microwave heating, are occasionally employed when accelerated drying is desired and the species being dried can withstand severe conditions without damage. None of these methods is of significant commercial importance. 

After the completion of the reaction, the solution was acidified to a pH of 4 with 2N sulfuric acid, followed by the addition of 50 ml of water. The solution was then extracted several times with ether. The extractant was dried over magnesium sulfate and the solvent was removed by evaporation at reduced pressure. Cold petroleum ether was then added to the resultant oily material to precipitate the product. The product was further washed with cold (10° C) petroleum ether and recrystallized several times from warm petroleum ether. The melting point of the final product was 73.5° C. Infrared spectrum of the product showed major absorption peaks relevant to the pure monomer (Figure 1). Under UV radiation, white flakes of the monomer solid turned deep blue (partial polymerization).
