AbstractRadiation decomposition and aerosol formation of various volatile organic compounds (VOCs) were examined to get information on a treatment of industrial off-gas. Model gases, air containing aromatic VOCs, chloroethenes and 1,2-dichloroethane, were sealed in batch reactors and irradiated with electron beam (EB) and gamma ray. For aromatic VOCs, G-values of decomposition in gamma ray irradiation were about 1.5 times larger than those in EB irradiation. The ratios of aerosol formation to decomposed aromatic VOCs were ranged from 30 to 66% on the basis of carbon. For chloroethenes except monochloroethylene, G-values of decomposition were 6 to 45 times larger than those of aromatic VOCs and the irradiated product was mainly gaseous compound. The G-values of decomposition in EB irradiation increased markedly with increase of chlorine atom in a molecule, while those in gamma ray irradiation were almost kept constant.

The aim of this article is to present a hands-on laboratory experiment, which enables students to become acquainted with the idea and some principles of green chemistry in the context of the manufacture and use of lacquers. Environmental concerns, particularly the regulations concerning Volatile Organic Compounds have resulted in a dramatic change in the coating markets and traditional solvent-based (SB) technologies are being replaced by new, environmentally friendly processes based on ultraviolet (UV) or electron beam (EB) curing. In this exercise, the technological processes of SB and UV lacquers production and application were simplified and adapted for a school laboratory. The obtained lacquers are fully functional products with repeatable, easily measurable properties, which depend on the composition directly. The proposed method in this exercise is based on guided inquiry, however, it may be realized in a more or less open form, depending on the teacher’s goals, needs, and preferences.
