Crown ether amines and methods of use
17 Oct 23
The invention provides a material comprising (i) a crown ether of formula (I) and/or (ii) a crown ether of formula (II), or a salt thereof, wherein each m independently is an integer from 1 to 8, each “” designates an optionally present bond and/or structure, each X independently is —N(R1)2, —N*(R1), —N**, —N*(R1)2+Z−, or —N**(R1)+Z−, provided at least one X is —N*(R1), —N**, —N*(R1)2+Z−, or —N**(R1)+Z−, wherein each R1 independently is hydrogen or C1-6 alkyl, each Z is optionally present and independently is a counterion to balance the charge on nitrogen, and * represents a bond to a remainder of the material, a method of making the material, and a method of using the material.

An integrity testing method for a porous medium in a housing having an interior separated by the medium into upstream and downstream portions, an inlet and an outlet communicating, respectively, with the upstream and downstream portions, the outlet connected to a closeable conduit, comprises filling the downstream portion and conduit with liquid, draining the upstream portion and filling it with gas while retaining liquid in the downstream portion, connecting a gas-filled testing volume to the downstream portion, maintaining gas pressure of a predetermined testing differential pressure in the upstream portion, the differential pressure being lower than a predefined bubble point of the medium, determining the pressure in the testing volume, the testing volume selected such that, when a medium is tested having a bubble point corresponding to the predefined bubble point, a pressure increase within the testing volume of about 100 mbar or more is obtained within 10 minutes.
