    Abstract: High selectivity to monoalkylene glycol is obtained by contacting in an associated moiety-forming zone alkylene oxide and a selectivity enhancing, dissociatable metalate anion under conditions sufficient to associate at least a portion of the alkylene oxide with metalate anion, and then contacting the associated moiety with water in a glycol-forming zone to form alkylene glycol. The alkylene glycol can be separated from metalate anion. Desirably, the metalate anion can be recycled to the associated moiety-forming zone.

    Abstract: A homogeneous catalytic process wherein a gaseous or vaporized reactant stream is continuously introduced into a liquid phase mixture containing (a) a volatile precious metal catalyst, and (b) methanol and/or ethanol as reactant or reaction product, at least a portion of the volatile precious metal being continuously removed from the liquid phase mixture by the effluent gas and/or vapor stream, and such effluent stream is an integral component of a cyclic process stream and/or a vent stream discharged from the process. The improvement is concerned with recovery of the volatilized precious metal and returning it to the liquid phase mixture which comprises passing one or both of said cyclic or vent streams through a liquid body of alcohol selected from the group consisting of methanol, ethanol and mixtures thereof at a temperature sufficiently low to effect the removal of at least a portion of the precious metal contained in said stream, and thereafter periodically or continuously introducing to the liquid phase mixture at least a portion of said liquid body containing the recovered precious metal.

    Abstract: A system and method for interfacing a patient with apparatus for monitoring gaseous components of the exhalation of said patient. The system includes a low dead space volume disc filter for blocking patient secretions and natural and manufactured humidification, improved sampling configuration, and apparatus for supporting endotracheal and tracheal tubes and the like with minimum discomfort to the patient. Special provision is made for supporting the endotracheal tube for a neonate, including a wire support requiring only minimal taping.
