Water, removal apparatus

Water Removal Apparatus—A device that attaches close to the outlet of the pyrolysis fiimace, used in the oxyhydropyrolysis set up to remove excess moisture from the sample stream. Both membrane counter flow driers or coalescing filters held at sub-ambient temperatures have been found to be suitable. 

Perform final purification of the iodine in the apparatus shown in Fig, 596. Put the iodine in vessel 4. Cool it with liquid nitrogen. Connect the apparatus to a fore pump. Evacuate the apparatus with cock 2 open (40 min), then close the cock, fill tube 1 with cold water, remove the liquid nitrogen so that vessel 4 acquires room temperature, and carefully heat it with the flame of a burner. When sublimation of the iodine is completed, cool the apparatus, carefully open cock 2,... 

Remove the bath with water, remove the rubber tube with a bent glass tip from the end of the apparatus, and pass the carbon(II) oxide through ammonia solutions of silver nitrate and copper(I) chloride poured into test tubes. What happens Does the carbon(II) oxide exhibit the same properties in these reactions How can one prove that carbon(II) oxide will evolve when the formed complex compound of copper(I) is heated ... 

Fig. 9.10. Apparatus for the determination of molecular weights of air-sensitive compounds by the isothermal distillation technique. Temperature fluctuations of the two solvents are minimized in this illustration by a Dewar filled with water. This apparatus is used in the following manner. In a dry box the sample is placed in a tared tube through sidearm A, the sidearm is then sealed off, the tube and remnant of the sidearm are weighed, and the tube is attached to the apparatus by glassblowing at B. A weighed portion of a standard is introduced into the other bulb, and the filling tube is sealed off. After evacuation, opening of the break-seal, and reevacuation, a measured portion of solvent is distilled into both arms of the apparatus. The process of equilibration is followed by periodic removal and measurement of the solvent from one arm. The solvent may be measured volumetricly in the liquid or gas stales, or by weight.

Butylene Oxide Clean protective clothing rubber gloves chemical worker s goggles self-contained breathing apparatus. If any ill effects occur, immediately remove person to fresh air and get medical help if breathing stops, start artificial respiration. Promptly flush with plenty of water remove all contaminated clothing and wash before reuse. Promptly flush with plenty of water for 15 minutes and get medical help.

The reaction gases from the electrolytic cell are passed through an iron drying tube containing freshly dehydrated KF to remove entrained HF and water. The apparatus ends in an iron drying tube containing KH. 

Imines, enamines, nitroalkenes, and N-sulfonylimines are conventionally prepared by condensation reactions in which liberated water is removed azeotropical-ly to drive the reaction to completion. Most of these reactions are catalyzed by p-to-luenesulfonic acid, titanium(IV) chloride, or montmorillonite KIO clay and require the use of a Dean-Stark apparatus and a large excess of volatile aromatic hydrocarbons such as benzene or toluene for azeotropic water removal. Varma et al. have successfully demonstrated the significance of a MW approach to generate nitroalkenes (Scheme 2.2-16), valuable synthetic precursors and building blocks in the...
