Abstract: A method for embedding a certain class of integral domains in division rings is devised. Integral domains $ A$ are constructed with a generalized valuation into a (noncommutative) totally ordered semigroup that need not be discrete. Then the multiplicative semigroup $ A\backslash \{ 0\} $ is expressed as an inverse limit of semigroups each of which is embeddable in a group. Thus $ A\backslash \{ 0\} $ can be embedded in a group $ G$. The main problem is to introduce addition on $ G$ in order that $ G$ becomes a division ring by the use of eventually commuting maps of inverse limits.
