Usage

General Description

Perchloronaphthalene is a synthetic, aromatic organic compound primarily used as a heat transfer medium. It is crystalline at room temperature, becoming clear and yellow when heated. This chemical is highly stable and has strong thermal oxidation resistance, making it ideal for use in closed systems at high temperatures. It is also known for excellent heat stability, low corrosiveness and toxicity levels, and a high boiling point. However, prolonged exposure can cause irritation to skin and eyes, and it may also be harmful if swallowed or inhaled. Therefore, it's necessary to handle this chemical with proper precaution.

Emission factors and importance of PCDD/Fs, PCBs, PCNs, PAHs and PM 10 from the domestic burning of coal and wood in the U.K.

This paper presents emission factors (EFs) derived for a range of persistent organic pollutants (POPs) when coal and wood were subject to controlled burning experiments, designed to simulate domestic burning for space heating. A wide range of POPs were emitted, with emissions from coal being higher than those from wood. Highest EFs were obtained for particulate matter, PM10, (～ 10 g/kg fuel) and polycyclic aromatic hydrocarbons (～ 100 mg/ kg fuel for ΣPAHs). For chlorinated compounds, EFs were highest for polychlorinated biphenyls (PCBs), with polychlorinated naphthalenes (PCNs), dibenzo-p-dioxins (PCDDs) and dibenzofurans (PCDFs) being less abundant. EFs were on the order of 1000 ng/kg fuel for ΣPCBs, 100s ng/ kg fuel for ΣPCNs and 100 ng/kg fuel for ΣPCDD/Fs. The study confirmed that mono- to trichlorinated dibenzofurans, Cl1,2,3DFs, were strong indicators of low temperature combustion processes, such as the domestic burning of coal and wood. It is concluded that numerous PCB and PCN congeners are routinely formed during the combustion of solid fuels. However, their combined emissions from the domestic burning of coal and wood would contribute only a few percent to annual U.K. emission estimates. Emissions of PAHs and PM 10 were major contributors to U.K. national emission inventories. Major emissions were found from the domestic burning for Cl1,2,3DFs, while the contribution of PCDD/F-ΣTEQ to total U.K. emissions was minor.

Preparation of decachlorocorannulene and other perchlorinated fragments of fullerenes by electrical discharge in liquid chloroform

The discharge reaction of decachlorocorannulene and other perchlorinated fragments of fullerenes is studied in liquid chloroform using electrical discharge. Results reveal various reaction products. It is shown that all the characterized products are perchlorinated fragments of C60.
