3.Petroleum distillates are a huge category that includes thousands of products. In fact, the term refers to anything that comes from the distillation, or cracking process, of petroleum crude oil.
4.The main difference of CC method and EBC method laid in the distillate(distillate gathered in strong acid solution for CC method).
7.In the process, all the liquid fractions of the petroleum are changed to gases, which move out of the still.
8.The results were showed, the optimum ratio of Gum Acacia and Maltodextrin 1:1,the optimum emulsion 0.4%, the optimum concentration of solid matter 40%, the optimum ratio of cinnaldehyde to wall material V∶m=1 mL∶10 g. The optimum processing conditions were as follows: inlet-air temperature 225 ℃,inner-speed of mixture 210 mL/h,air pressure of ejector 180 kPa.
9.Thus, 100 parts AA(contg. 0.02% hydroquinone), 105 parts ECH, 0.29% by wt. chromium(Ⅲ) naphthenate, 0.25% by wt. N,Ndimethylaniline were mixed. The mixture was reacted at 90 ℃ for 3 h, then removed the excessed ECH in vacuo, under 399.8 Pa at 95～98 ℃ to give the title compound in 98% yield.
10.Something, such as the thread of a screw or the spiral condenser in a still, that resembles a worm in form or appearance.
