Title (EN) ENVIRONMENTALLY-SAFE SOLVENT COMPOSITIONS UTILIZING 1-BROMOPROPANE THAT ARE STABILIZED, NON-FLAMMABLE, AND HAVE DESIRED SOLVENCY CHARACTERISTICS
(FR) COMPOSITIONS DE SOLVANT SANS DANGER POUR L'ENVIRONNEMENT, A BASE DE 1-BROMOPROPANE, STABILISEES, ININFLAMMABLES ET AYANT LES CARACTERISTIQUES DE SOLVABILITE VOULUES
Abstract:
(EN) Environmentally-safe, low volatile-organic-compound (VOC), solvent compositions containing 1-bromopropane are disclosed. The compositions contain additional compounds to adjust the solvency characteristics and/or stabilize the 1-bromopropane. To adjust the solvency characteristics while inhibiting flammability, n-propanol or hydrofluorocarbon in a precise amount is added. To stabilize the compositions, a variety of stabilizing agents are added, one of which contains: tert-butyl alcohol or n-propanol; dimethoxymethane or diethoxymethane; and a mixture of 2 or more epoxides selected from the group: butylene oxide, propylene oxide, cyclohexene oxide, epichlorohydrin, and epibromohydrin. The composition is easily used with conventional cleaning techniques and easily incorporated into existing cleaning apparatuses such as vapor degreasers, motion picture film cleaning machines, aerosol applications and the like.
(FR) L'invention concerne des compositions de solvant sans danger pour l'environnement, du type à composé organique faiblement volatil, à base de 1-bromopropane. Lesdites compositions renferment des composés additionnels pour l'ajustement des caractéristiques de solvabilité et/ou la stabilisation du 1-bromopropane. On ajoute encore du n-propanol ou un fluorocarbure en quantité précise pour ajuster les caractéristiques de solvabilité tout en inhibant l'inflammabilité. Pour stabiliser les compositions, on ajoute aussi une série de stabilisants, dont l'un contient les éléments suivants: alcool tert-butylique ou n-propanol; diméthoxyméthane ou diéthoxyméthane; et un mélange de deux ou plus de deux époxydes choisis parmi: oxyde de butylène, oxyde de propylène, oxyde de cyclohexène, épichlorohydrine, et épibromohydrine. On peut facilement utiliser ce type de composition avec les techniques de nettoyage classiques, et on peut facilement l'incorporer à des appareils de nettoyage existants, à savoir par exemple: dégraisseurs à la vapeur, machines de nettoyage pour film cinématographique, applications aérosol et autres.
