ASTM E133-1992(2005) Standard Specification for Distillation Equipment《蒸馏设备的标准规范》.pdf

1、Designation: E 133 92 (Reapproved 2005)Standard Specification forDistillation Equipment1This standard is issued under the fixed designation E 133; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last revision. A number

2、in parentheses indicates the year of last reapproval. Asuperscript epsilon (e) indicates an editorial change since the last revision or reapproval.This standard has been approved for use by agencies of the Department of Defense.1. Scope1.1 This specification covers distillation equipment used inthe

3、following ASTM test methods: D86, D 850, and (forapproved alternative requirements only) Test Method D 1078.1.2 Some items of equipment included in this specificationare common to all methods; other items are not. Therefore,those portions of this specification pertinent to the need mustbe selected.1

4、.3 The values stated in inch-pound units are to be regardedas standard. The values given in parentheses are mathematicalconversions to SI units that are provided for information onlyand are not considered standard.2.

7、ecification E 1405.5. Condenser and Cooling Bath5.1 Typical approved types of condenser and cooling bathare included in Fig. 1 and Fig. 2. These items are common toall methods covered by this specification.5.2 The condenser shall be made of seamless brass tubing,22 in. (55.88 cm) in length. It shall

8、 be916 in. (14.29 mm) inoutside diameter, and shall have a wall thickness of 0.031 to0.036 in. (0.08 to 0.09 cm).5.3 The condenser shall be set so that approximately 15.5 in.(39.4 cm) of the tube will be in contact with the coolingmedium, with about 2 in. (5 cm) outside the cooling bath at theupper

9、end, and about 412 in. (11 cm) outside at the lower end.The length of tube projecting at the upper end shall be straightand shall be set at an angle of 75 with the vertical. The sectionof the tube inside the cooling bath may be either straight orbent in any suitable continuous, smooth curve. The ave

10、ragegradient shall be 0.26 in. (0.66 cm)/linear in. (2.54 cm) ofcondenser tube (sine of angle of 15), and no section of theimmersed portion of the condenser tube shall have a gradientless than 0.24 in. (0.61 cm) nor more than 0.28 in. (0.71 cm)/linear in. of tube. The projecting lower portion of the

11、 condensertube shall be curved downward for a length of 3 in. (7.62 cm)and slightly backward so as to ensure contact with the wall ofthe receiving graduate at a point approximately 1 to 114 in.(2.54 to 3.18 cm) below the top of the graduate when it is inposition to receive the distillate. The lower

12、end of the con-denser tube shall be cut off at an acute angle so that the tip maybe brought into contact with the wall of the cylinder.5.4 The capacity of the cooling bath shall be not less than340 in.3(5.55 L) of cooling medium. The arrangement of thetube in the cooling bath shall be such that its

13、center line shallbe not less than 114 in. (3.18 cm) below the plane of the top of1This specification is under the jurisdiction of ASTM Committee E41 onLaboratory Apparatus and is the direct responsibility of Subcommittee E41.01 onApparatus.Current edition approved Oct. 1, 2005.

(1.91cm) above the floor of the bath at its exit.5.5 Clearances between the condenser tube and t

16、he walls ofthe bath shall be at least12 in. (1.27 cm) except for the sectionsadjacent to the points of entrance and exit. Multiple installa-tions are permissible, provided they conform to the dimen-sional requirements and the capacity of the bath is not less than340 in.3(5.55 L)/tube.6. Metal Shield

17、 or Enclosure for Flask6.1 Type 1 Shield (Fig. 1) is 19 in. (48.26 cm) high, 11 in.(27.94 cm) long, and 8 in. (20.32 cm) wide, made of sheetmetal of approximately 22 gauge. It shall have a door on onenarrow side, and two openings 1 in. (2.54 cm) in diameter,equally spaced in each of the two narrow s

18、ides, with a slot cutin one side for the vapor tube. The centers of these fouropenings shall be 812 in. (21.59 cm) below the top of theshield. There shall be three14-in. (1.27 cm) holes in each of thefour sides, with their centers 1 in. above the base of the shield.6.2 Type 2 Shield (Fig. 2)is1714 i

19、n. (44.45 cm) high, 8 in.(20.32 cm) long, and 8 in. wide, made of sheet metal ofapproximately 22 gauge, with a window on the front side. Theopen bottom of the shield shall be spaced approximately 2 in.(5 cm) from the base of the unit. The rear of the shield shallhave an elliptical hole for the vapor

20、 tube. A flask-adjustingknob shall be located on front of the shield for adjusting theflask support. Also, a heat-adjusting indicating dial shall beused to provide stepless heat control when the electric heater isused. The entire mechanism shall be built into the bottomportion of the shield. When an

21、 electric heater is employed, theportion of the shield above the board shall be the same as withthe gas burner, but the part below may be omitted.7. Heat Source7.1 Gas Burner (Fig. 1), so constructed that sufficient heatfrom the available gas can be obtained to distill the product atthe specified ra

22、te. A sensitive regulating valve and gas pressuregovernor to give complete control of heating may be provided.7.2 Electric Heater (Fig. 2), may be used instead of a gasburner, provided it is capable of bringing over the first dropFIG. 1 Apparatus Assembly Using Gas BurnerFIG. 2 Apparatus Assembly Us

Heater units of low heatretention, adjustable from 0 to 1000 W, have been foundsatisfactory.8. Flask Support8.1 Type 1 for Use with Gas Burner (Fig. 1)Aring support

24、of the ordinary laboratory type, 4 in. (10.2 cm) or larger indiameter, supported on a stand inside the shield or on aplatform, and adjustable from the outside of the shield, may beused.8.1.1 Two ceramic or hard heat-resistant boards,18 to14 in.(3.2 to 6.4 mm) in thickness, shall rest upon the ring o

(7.6 to10 cm) in diameter and outside line dimensions slightly smallerthan the inside boundaries of the shield.8.1.2 The second or flask-support board shall be slightlysmaller i

26、n outside dimensions than the first board and shallhave a centered opening conforming to the dimensions pre-scribed in Table 1. It shall be18 to14 in. in thickness at thecenter-hole rim. This flask-support board may be movedslightly in accordance with the directions for placing thedistillation flask

27、, and direct heat shall be applied to the flaskonly through the opening in this board.8.2 Type 2 for Use with Electric Heater (Fig. 2)The top ofthe electric heater shall consist of a ceramic or hard heat-resistant flask-support board with a centered hole as specifiedin Table 1, and a thickness of18

28、to14 in. at the center-hole rim.Provisions shall be made for moving the heater unit, with itstop, in order to place the distillation flask so that direct heatshall be applied to the flask only through the opening in theflask-support board.9.
