Title (EN) 1,3,5-DIOXAZINE DERIVATIVES, METHOD OF PREPARATION AND APPLICATION THEREOF AS SULFIDE SCAVENGER
(FR) DÉRIVÉS DE 1, 3, 5-DIOXAZINE, LEUR PROCÉDÉ DE PRÉPARATION ET LEUR APPLICATION COMME PIÉGEUR DE SULFURE
Abstract:
(EN) The present disclosure relates to 1,3,5-dioxazine derivatives of formula (I) capable of reducing or eliminating hydrogen sulfide and other objectionable sulfides from oil field produced hydrocarbon fluids such as petroleum, fuel oil, gasoline, diesel, liquid propane, liquid butane, an aquaculture and production/processing of syngas/natural gas. The present disclosure further provides a method for preparing 1, 3, 5-dioxazine derivatives of formula I, and a method for scavenging sulfur-based species including, but not limited to hydrogen sulfide or alkyl/aryl mercaptans from a medium.
(FR) La présente invention concerne des dérivés de 1, 3, 5-dioxazine de formule I capables de réduire ou d'éliminer le sulfure d'hydrogène et d'autres sulfures indésirables à partir de fluides hydrocarbonés produits par le champ pétrolifère tels que le pétrole, l'essence, le diesel, le propane liquide, le butane liquide, l'aquaculture et la production/le traitement de gaz de synthèse/gaz naturel. La présente invention concerne en outre un procédé de préparation de dérivés de 1, 3, 5-dioxazine de formule I, et un procédé de piégeage d'espèces à base de soufre comprenant, mais sans s'y limiter, du sulfure d'hydrogène ou des alkyl/aryl mercaptans à partir d'un milieu.
