Creosote removed; the "heavy oil", which sinks; and the "anthracene oil", which when cold is mostly solid and greasy, of a buttery consistence. Creosote refers to the portion of coal tar which distills as "heavy oil", typically between 230–270 °C, also called "dead oil"; it sinks into water but still is fairly liquid. Carbolic acid is produced in the second fraction of distillation and is often distilled into what is referred to as "carbolic oil". Commercial creosote will contain substances from six groups. The two groups occur in the greatest amounts and are the products of the distillation process—the "tar acids",
Name-letter effect countries liking those letters relatively more. As in the first study, the second one also included a task relating to disliking letters. Subjects were asked to select the six letters they liked the least. As before, merely having a letter in one's own name significantly reduced the chances of disliking it. This task revealed an asymmetry in the letter preference hierarchy. While there was a large consensus within each of the 12 languages as to which letters were least preferred, there was not much consensus at all around the most preferred letters.
