Cyclodienes. These are polychlorinated cycHc hydrocarbons with endomethylene-bridged stmctures, prepared by the Diels-Alder diene reaction. The development of these insecticides resulted from the discovery in 1945 of chlordane, the chlorinated adduct of hexachlorocyclopentadiene and cyclopentadiene (qv). The addition of two Cl atoms across the double bond of the ftve-membered ring forms the two isomers of chlordane [12789-03-6] or l,2,4,5,6,7,8,8-octachloro-2,3,3t ,4,7,7t -hexahydro-4,7-methano-lJT-indene, QL-trans (mp 106.5°C) and pt-tis (32) (mp 104.5°C). The p-isomerhas signiftcantiy greater insecticidal activity. Technical chlordane is an amber Hquid (bp 175°C/267 Pa, vp 1.3 mPa at 25°C) which is soluble in water to about 9 fig/L. It has rat LD qS of 335, 430 (oral) and 840, 690 (dermal) mg/kg. Technical chlordane contains about 60% of the isomers and 10—20% of heptachlor. It has been used extensively as a soil insecticide for termite control and as a household insecticide.

Ministry of Efealth, Labor, and Welfare, Japan (MEfLW) The unit responsible for the improvement and promotion of social welfare, social security, and public health is the Pharmaceutical Affairs bureau of the ministry. It is one of the nine bureaus within the Pharmaceuticals and Cosmetics Division and is responsible for review and licensing of all medicinal products and cosmetics. In Japan, it acts as the focal point for ICH activities. Technical advice on ICH matters is obtained through MHLW s regulatory expert groups. 

The number of application grows in the chemical / process technology. Quite often we only speak of chemical technology and subdivide this into active technical ceramics (e.g. sensors, see elsewhere in this chapter) and passive technical ceramics (e.g. vessels, pumps, filters and catalytic agent carriers). When ceramic parts are exposed to corrosion caused by a metallic or non-metallic smelt, they are provided with a coating (see elsewhere in this chapter). 

Acyloin condensation.5 The acyloin condensation of 1,4- to 1,6-diesters according to the Ruhlmann version using chlorotrimethylsilane and highly dispersed sodium is markedly simplified by sonochemical activation. Technical grade ClSi(CH3)3 and small cubic pieces of sodium can be used.

Quality assurance activities (technical reviews, for instance, or onsite engineering and construction inspection) can present particular challenges. Some cultures see the activities related to quality assurance as an indicator of lack of trust. Resentments may arise. Being sensitive to these perceptions, and talking through them, is critical.
