Key words. The reactions of a number of model compounds, in particular, cyclohexyl phenyl sulfide (CPS), were studied in the work of Katritzky [ 1, 2, 4] to obtain a better understanding of the mechanism for the dissociation of SH bonds under aquathermolysis conditions. The major products of the reaction of CPS with water at 250°C.
Water Wave/Tide/Level Meter 2.0. Ken Sheridan and I have been working on a device to accurately measure the level of water in a tank, or on a lake, river or estuary. This document details the result of this work. Thanks Ken for the write-up. Over the years since we first posted this many people have built these circuits with varying degrees of .
Water meter Question - Extremely high bill & No leak. 20 Replies Log in or sign up to reply 1 . Does anyone have knowledge about if water meters can erroneously jump? . The water level in one of the toilet's tank was too high and water was flowing into the overflow tube. It was noticeable in the water …
N-CYCLOHEXYL-2-BENZOTHIAZOLESULFENAMIDE. The split of sulfur 8-membered ring structure into shorter chains provides rubber vulcanization process. The split are liked with cure sites (some of the solid bonds in the molecule) on rubber molecules, resulting in forming sulfur bridges typically between 2 …

Oct 19, 2016· The Sulphide Ion-Selective Electrode has a solid-state crystal membrane. The electrode is designed for the detection of sulphide ions (S-2 ) in aqueous solutions and is suitable for use in in both field and laboratory applications. The Sulphide Ion is a bivalent anion.
The mercaptan and H2S content in crude oil is determined by a two-endpoint argentometric titration (see also Metrohm Application Bulletin 135) based on ASTM D3227-83 and UOP163-67. Application Note AN-PAN-1026 describes the respective applications and is available free from Metrohm Process Analytics.
To remove low levels of hydrogen sulfide, install an activated carbon filter. The filter must be replaced periodically to maintain performance. Frequency of replacement will depend on daily water use and concentration of hydrogen sulfide in the water. Hydrogen sulfide concentrations up to about 5 to 7 ppm can be removed using an oxidizing filter.

Aquathermolysis is often proposed as a method to reduce the viscosity of heavy oils. In the present work we have investigated the aquathermolysis reaction of cyclohexyl phenyl sulfide in water medium by means of density functional theory. The water molecule was considered as a reagent and as a catalyst.
