  • Process for preparing polyols
    Patent number: 4282387
    Abstract: The invention describes an improved process for preparing polyols by reacting a mono-epoxy compound such as propylene oxide with a hydroxyl-containing initiator compound such as glycerine in the presence of a catalyst, the improvement being that the catalyst is added in the form of a calcium, strontium or barium salt of an organic acid such as acetic acid.Polyols prepared by this process can be employed to prepare polyurethanes without removing the catalyst.
