摘要: A composition and apparatus for dry chemical fire extinguishing material is disclosed. The composition has a dry chemical fire extinguishing agent mixed with substantially spherical microspheres. The apparatus has a container for retaining the composition and a delivery nozzle. Also in the container is a propellant to convey the composition from the container to the nozzle. A fire is contacted by the composition to extinguish the fire.

摘要: Solids are separated from aqueous 1,4-butynediol solutions by passing a solids-containing aqueous butynediol solution in the downflow mode through a column and thus bringing it into contact with a solvent which has a lower density than the solids-containing butynediol solution and forms a second phase with the latter, with the solvent rising in countercurrent to the aqueous butynediol solution, the solid accumulating at the interface between the aqueous butynediol and the solvent and the solid being removed from the column by taking off a mixture of aqueous butynediol and solvent.
