For this kind of toxicity specific structural prerequisites arc not required, thus leading to some spread of the compounds in stmctural space. About five of nine layers showed little tendency to duster, some of them with quite specifically acting... 

It is best now to proceed as in the Skraup Synthesis (p. 297) and warm the mixture over an asbestos-covered gauze with a Bunsen flame until the reaction starts, and have at hand a duster soaked in cold water so that when the reaction starts, the heating can be at once removed and the duster wrapped round the shoulders of the flask to aid condensation. 

If a liquid which is being heated in a beaker or a conical flask catches fire, it is frequently sufficient to turn off the gas (or other source of heating) below and then at once to stretch a clean duster tightly over the mouth of the vessel. The fire quickly dies out from lack of air, and the (probably valuable) solution is recovered unharmed. 

A small fire (for example, hquid in a beaker or flask, or an oil bath) may usually be extinguished by covering the opening of the vessel with a clean damp cloth or duster the fire usually dies out from lack of air. For larger fires, dry sand may be employed. Buckets of dry sand should be distributed round the laboratory and should be strictly reserved for this purpose. Most fires on the laboratory bench can be smothered by... 

Nonwoven wipe categories include products for babies and adults, the food service and electronics industries, medical and clean room appHcations, industrial cleaning, computer diskettes, and household products such as dusters, tea towels, shoe cleaning cloths, towelettes, and hand towels. Nonwoven fabrics are used to filter air, water, petroleum (qv), food, and beverages. Nonwovens loaded with abrasives, cleansers, or finishes can be found in a variety of products used by many industries and in many homes to scour or poHsh. Also, a majority of garments designed to protect industrial workers and consumers from hazardous environments are made from nonwoven fabrics.

Turn off the source of the leak and limit the spread of fluid by means of mop, dusters, rags, sand or diversion Absorb spillage and shovel into buckets, and remove to a safe place, dilute greatly with running water and/or dilute with dispersing agent and water (as with ammonia solution, ethanol, methanol and formaldehyde solution)... 

The coordination chemistry of SO2 has been extensively studied during the past two decades and at least 9 different bonding modes have been established.These are illustrated schematically in Fig. 15.26 and typical examples are given in Table 15.17.1 It is clear that nearly all the transition-metal complexes involve the metals in oxidation state zero or -bl. Moreover, SO2 in the pyramidal >7 -dusters tends to be reversibly bound (being eliminated when...

A similar reaction patliway was found for tlie S u2 substitution of an epoxide witli a litliiuni aiprate duster [ 124]. tn contrast to tliat in tlie MeBr reaction, tlie ste-reodieniistry of tlie dectropb dic carbon center is already inverted in tlie transition state, providing tlie reason for tlie prefetLed "rrons-diaxial epoxide-opetiing" widely observed in syntlietic studies. Hie TS for tlie S 2 reaction of cydobexene oxide is shown in Eq. 10.12. 

Hie origin of tlie acceleration produced by BF in epoxide alkylation teactions has been examined tlieotetically [124], A plausible patliway for BF patLicipation in tlie epoxide-opening is sliown in Fig. 10.5.
