20、ndards, Vol 05.01.5.2 Grades 100 and 100LL represent two aviation gasolinesidentical in antiknock quality but differing in maximum leadcontent and color.

21、35 and 115/145 appeared in the 1967 version of this specification. U.S.Military Specification MIL-G-5572F, dated January 24, 1978 (withdrawnMarch 22, 1988), also covers grade 115/145 aviation gasoline, and isavailable as a research report.45.3 Although the grade designations show only a singleoctane

22、 rating for each grade, they must meet a minimum leanmixture motor rating and a minimum rich mixture superchargerating (see X1.2.2).6. Materials and Manufacture6.1 Aviation gasoline, except as otherwise specified in thisspecification, shall consist of blends of refined hydrocarbonsderived from crude

23、 petroleum, natural gasoline, or blends,thereof, with synthetic hydrocarbons or aromatic hydrocar-bons, or both.6.2 AdditivesMandatory, shall be added to each grade ofaviation gasoline in the amount and of the compositionspecified in the following list of approved materials.6.2.1 Tetraethyl Lead, sh

24、all be added in the form of anantiknock mixture containing not less than 61 mass % oftetraethyl lead and sufficient ethylene dibromide to provide twobromine atoms per atom of lead. The balance shall contain noadded ingredients other than kerosine, an approved oxidationinhibitor, and blue dye, as spe

25、cified herein. The maximumconcentration limit for each grade of gasoline is specified inTable 1.6.2.1.1 If mutually agreed upon by the fuel producer andadditive vendor, tetraethyl lead antiknock mixture may bediluted with 20 mass % of a mixed aromatic solvent having aminimum flash point of 60C accor

26、ding to Test Methods D93when the product is to be handled in cold climates. The TELcontent of the dilute product is reduced to 49 mass %, so thatthe amount of antiknock additive must be adjusted to achievethe necessary lead level. The dilute product still delivers twobromine atoms per atom of lead.6

27、.2.2 DyesThe maximum concentration limits in eachgrade of gasoline are specified in Table 1.6.2.2.1 The only blue dye that shall be present in thefinished gasoline shall be essentially 1,4-dialkylaminoanthraquinone.6.2.2.2 The only yellow dyes that shall be present in thefinished gasoline shall be e

28、ssentiallyp-diethylaminoazobenzene (Color Index No. 11021) or 1,3-benzenediol 2,4-bis (alkylphenyl)azo-.6.2.2.3 The only red dye that shall be present in the finishedgasoline shall be essentially alkyl derivatives of azobenzene-4-azo-2-naphthol.6.2.2.4 The only orange dye that shall be present in th

29、efinished gasoline shall be essentially benzene-azo-2-napthol(Color Index No. 12055).6.3 AdditivesThese may be added to each grade of avia-tion gasoline in the amount and of the composition specified inthe following list of approved materials.5The quantities andtypes shall be declared by the manufac

30、turer. Additives addedafter the point of manufacture shall also be declared.6.3.1 AntioxidantsThe following oxidation inhibitors maybe added to the gasoline separately, or in combination, in totalconcentration not to exceed 12 mg of inhibitor (not includingweight of solvent) per litre of fuel.6.3.1.
