3.1 distillation
process of evaporation and condensation of a liquid
3.2 mineral flux
flux which may be of carbochemical or petrochemical origin or a mixture of both
4 Principle
Petroleum cut-back and fluxed bituminous binders are distilled at a controlled rate until the temperature of the liquid reaches 360 °C. The volumes of distillate and residue obtained over specified temperature ranges are measured. The residue from the distillation and also the distillate can be tested as required.
5 Apparatus
Usual laboratory apparatus and glassware, together with the following:
5.1 Distillation flask, 500 ml and with side-arm, of dimensions given in Figure 1.
5.2 Heating system. Equipment needed when using a gas burner or equivalent (see Figure 3).
5.2.1 Shield, of steel, lined with 3 mm of suitable thermal insulation material and fitted with transparent mica windows of the form and dimensions shown in Figure 2, which is used to protect the distillation flask from air currents and to reduce radiation.
5.3.2 Electric heater (replacing items 6, 7 and 8 in Figure 3), with a heating plate adequately surfaced to support the distillation flask and designed so as to efficiently transfer the heat. The heating plate shall be of sufficient dimensions to support the shield over its entire base. The heater shall be equipped with a transformer capable of controlling from 0 W to 750 W.
5.3.3 Height adjustable platform, to support the electric heater.
5.4 Heating system. Equipment needed when using an electric heating mantle.
5.4.1 Electric heating mantle (replacing items 4, 6, 7 and 8 in Figure 3), of adequate inner size to fit the 500 ml distillation flask and completely embed the 200 ml product sample once filled into the distillation flask (see 6.3.1). The heating mantle shall be completed with a removable insulation collar to cover the part of the distillation flask emerging from the heating mantle. The heating mantle shall be equipped with a transformer capable of controlling from 0 W to 750 W.
