Synthesis of SYEP Plasticizer.

Abstract : SYEP, a new plasticizer was synthesized by difluoramination of 1.3- bisfluorodinitroethoxy)acetone. Phase I of this program involved demonstration of the feasibility of this synthesis and determination of physical properties of SYEP. Phase II dealt with study of reaction variables with emphasis of improving the yield of 1,3-bis(fluorodinitroethoxy)isopropanol, the key-intermediate, from fluorofinitroethanol and epichlorohydrin, and its oxidation to 1,3- bis(fluorodinitroethoxy)acetone. One hundred grams of SYEP was synthesized during Phase II. Phase III involved a scale-up operation which resulted in production of 5 lb of SYEP.
