When fuel system sumps, filters and storage tanks are drained, they contain EGME/DiEGME and create a personnel hazard. Acetals and ketals of reduced sugars represent viable alternatives to glycol based additives. They are inexpensive, fuel stable for at least one year and show similar icing inhibitor characteristics. This paper summarizes the synthesis and fuel studies for these compounds.","PeriodicalId":20402,"journal":{"name":"Preprints-American Chemical Society Division of Petroleum Chemistry","volume":"12 1","pages":"542-544"},"PeriodicalIF":0.0,"publicationDate":"1997-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79995377","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
