Abstract
This invention relates to apparatus for forming a gaseous mixture comprising a carrier gas substantially saturated with vapors of a normally liquid chemical material, under conditions of high throughput. The apparatus of the invention is adapted to pass a carrier gas through a normally liquid chemical material in a pressure vessel, while controlling the temperature and pressure of the system, thereby controlling the concentration of the vaporous, normally liquid chemical material in the carrier gas and to assure the formation of a substantially saturated gaseous mixture. Before exiting the pressure vessel the initial dispersion of carrier gas and chemical material is contacted with means adapted to retard passage of liquid chemical substance from the pressure vessel and to enhance the degree of saturation of the carrier gas. The invention is also directed to the use of a gaseous mixture of curing agent and carrier gas to cure low temperature curing sand molding compositions.
