7、llon.4.Apparatus4.1 Extraction Apparatus(see Fig.1 and Fig.2),consistingof the parts described in 4.1.1 4.1.6.4.1.1 Extraction Flask,a wide-neck Erlenmeyer flask of 1-Lcapacity.4.1.2 Condenser,a condenser in the form of a metal coilapproximately 25 mm in diameter and 50 mm in lengthattached to,and w
8、ith the ends projecting through a lid ofsufficient diameter to cover the neck of the flask as shown inFig.1.The coil should be made from stainless steel,tin,tin-plated copper,or tin-plated brass tubing having an outsidediameter of 5 to 8 mm and a wall thickness of 1.5 mm.Ifconstructed of tin-plated
9、copper or brass,the tin coating shallhave a minimum thickness of 0.075 mm.The exposed surfaceof the coil for cooling purposes is about 115 cm2.4.1.3 Extraction ThimbleThe extraction thimble should beof a refractory porous material,pore size index P15,25 mm indiameter by 70 mm in height,weighing not
10、less than 15 g andnot more than 17 g.The thimble shall be suspended from thecondenser coil by means of a basket so that it hangs approxi-mately midway between the surface of the extracting solventand the bottom of the condenser coil.4.1.4 Thimble BasketThe thimble basket shall becorrosion-resistant,
11、shall be made of platinum,stainless steel,nickel-chromium alloy,or similar material,and shall meet therequirements of Fig.2.4.1.5 Water CupA water cup shall be used when testing asample having a high-water content(see Fig.1b).The cup shallbe made of glass,shall be conical in shape,shall be approxi-m
12、ately 20 mm in diameter and 25 mm deep,and shall have acapacity of approximately 3 mL.Aglass hook fused on the rimat one side is so shaped that when hung on the condenser thecup hangs with its rim reasonably level.In this procedure,thethimble basket is suspended either as shown in Fig.1a bymeans of
13、the corrosion-resistant wire looped over the bottom ofthe condenser coil and attached to the basket supports or as inFig.1b where the wire supports of the basket are attached tohooks soldered to the underside of the condenser lid.4.1.6 Source of Heat,a source of heat,preferably a hot plate,suitable
14、for vaporizing toluene.1This test method is under the jurisdiction of ASTM Committee D31 on Leatherand is the direct responsibility of Subcommittee D31.08 on Fats and Oils.This testmethod was developed in cooperation with the American Leather Chemists Assn.(Method H 231957).Current edition approved
