Abstract: A coalescing element for aggregating droplets of an emulsion. The coalescing element includes a nonwoven web substrate. A coalescer that includes the coalescing element can also include a housing and a fluid inlet and a fluid outlet each in fluid communication with the coalescing element. The coalescing element and coalescer may be useful for emulsions that form in solvent extraction/electrowinning copper processing and for other emulsions.

Abstract: A perfluoropolyether thiol compound comprises a perfluoropolyether segment, at least one mercapto group (—SH), and at least one intervening divalent carbonylimino moiety (—C(═O)—NR—, wherein R is hydrogen or alkyl). The compound can be produced, for example, by a ring-opening reaction of thiolactones with perfluoropolyether-substituted, primary or secondary amines. The compound can be used, for example, as a polymerization chain transfer agent, as an intermediate for the preparation of functional group-containing fluorochemical derivatives such as disulfides, and as a fluorinated surface treatment.

Abstract translation: 全氟聚醚硫醇化合物包括全氟聚醚链段，至少一个巯基（-SH）和至少一个插入的二价羰基亚氨基部分（-C（= O）-NR-，其中R是氢或烷基）。 该化合物可以例如通过硫代内酯与全氟聚醚取代的伯或仲胺的开环反应来制备。 该化合物可以用作例如作为制备含二氟化物的含官能团的含氟化合物衍生物的中间体的聚合链转移剂，作为氟化表面处理。
