  • Methylchloroform stabilizer composition employing an alkynyl sulfide
    Patent number: 4309301
    Abstract: An alkyl alkynyl sulfide can be employed to stabilizer methylchloroform against reaction with the common metals of construction. Stabilization is enhanced by combining with other known stabilizers. Nitroalkanes, alkyl nitrates or alkynols may be employed to eliminate the need of dioxane and alkylene oxides, while the use of the alkyl nitrates or alkynols eliminates the need for a nitroalkane in the stabilizer formulation.
