Multiplicative ideal theory has at first been developed for (commutative) integral domains. We concern here generalizations of the theory to (commutative) rings with zerodivisors. At first, Manis  defined a valuation for a commutative ring with zerodivisors, and generalized basic properties of a valuation on a domain(1). Using the results of Manis, Griffin  extended the notion of prufer domain for commutative rings with zerodivisors, and extended conditions under which a ring is a prufer ring. And Larsen generalized the notion and properties of almost Dedekind domain for rings with zerodivisors , generalized primary ideal structure of a prufer domain for a ring with zerodivisors. Also he extended the notion of finite character and characterizations of a prufer domain with finite character for a ring with zerodivisors . Next Hinkle-Huckaba  defined a Kronecker function ring for a ring with zerodivisors and generalized a property of a Kronecker function domain(2). Besides, Kennedy  extended the notion of Krull domain for a ring with zerodivisors and generalized some properties of a Krull domain for a ring with zerodivisors(3). Here we generalize all of multiplicative ideal theory for a ring with zerodivisors. The subjects remaining for generalizations are as follows: 1. We know by Griffin  the extension of conditions of a prufer domain to a prufer *-multiplication domain, and a relationship between a prufer v-multiplication domain and a domain of Krull type.
