miscible definition
miscible herein means that two components, which in this case are the PAG and the aqueous alcohol working fluid is a physical blend, i.e., the two components: (1) maintain a single phase for a period of at least 24 hours at ambient temperature, and (2) during the same time period, the two components do not exhibit turbidity. If the two components exhibit any turbidity or separation then the two components are immiscible. For example, the miscibility of the PAGs and aqueous alcohol may be from about 10 wt % to about 90 wt % in one embodiment, and from about 10 wt % to about
