Preparation
Abietic acid is extracted from tree rosin. The pure material is a colourless solid, but commercial samples are usually glassy or partly crystalline yellowish solid that melts at temperatures as low as 85 °C (185 °F).
It belongs to the abietane diterpene group of organic compounds (compounds derived from four isoprene units). It is used in lacquers, varnishes, and soaps, and for the analysis of resins and the preparation of metal resinates. It is found in Pinus insularis (Khasi Pine), Pinus kesiya Royle, Pinus strobus (Eastern White Pine), Pinus sylvestris (Scots Pine).

Famous quotes containing the word preparation:
“It’s sad but true that if you focus your attention on housework and meal preparation and diapers, raising children does start to look like drudgery pretty quickly. On the other hand, if you see yourself as nothing less than your child’s nurturer, role model, teacher, spiritual guide, and mentor, your days take on a very different cast.”
—Joyce Maynard (20th century)
“With memory set smarting like a reopened wound, a man’s past is not simply a dead history, an outworn preparation of the present: it is not a repented error shaken loose from the life: it is a still quivering part of himself, bringing shudders and bitter flavours and the tinglings of a merited shame.”
—George Eliot [Mary Ann (or Marian)
“Living each day as a preparation for the next is an exciting way to live. Looking forward to something is much more fun than looking back at something—and much more constructive. If we can prepare ourselves so that we never have to think, “Oh, if I had only known, if I had only been ready,” our lives can really be the great adventure we so passionately want them to be.”
—Hortense Odlum (1892–?)
