Owens, Thomas R.; Clark, Peter D. published an article in 2011, the title of the article was Triazine chemistry: removing H2S and mercaptans.COA of Formula: C9H21N3O3 And the article contains the following content:
Arguably, one of the most common methods for removing low levels of hydrogen sulfide from natural gas (i.e., < 1 ton of sulfur per day) is triazine based chem. scavengers. Triazines are produced from the reaction of primary amines such as monoethanolamine or methylamine with aldehydes, specifically, formaldehyde. Despite their wide spread usage throughout the industry only a few studies have been published regarding the reaction of triazines with hydrogen sulfide. In studies conducted by Bakke and coworkers, the kinetics and reaction products (i.e., dithiazines) for the reaction of different triazines with hydrogen sulfide were investigated under various pH conditions. Another type of sulfur compounds that intermittently needs to be removed from hydrocarbon streams is mercaptans. Although some in the industry have indicated triazines can be used remove mercaptans, there is no specific information in the open literature regarding the reaction of triazines with mercaptans in regards to reaction products or kinetics. In this paper, we present a thorough background into the chem. of triazines, in particular, their reaction with hydrogen sulfide and potential problems produced from the formation of dithiazine. In addition, the current results of a systematic study for the reaction of two triazines, 1,3,5-tris(2-hydroxyethyl)hexahydro-s-triazine (1) and 1,3,5-trimethylhexahydro-s-triazine (2) with different mercaptans: methanethiol (MeSH), ethanethiol (EtSH) and n-propanethiol (n-PrSH) will be presented. The experimental process involved the reaction of 2,2',2''-(1,3,5-Triazinane-1,3,5-triyl)triethanol(cas: 4719-04-4).COA of Formula: C9H21N3O3
