ble kingdoms (see Palmitin). It dissolves solid fats, especially at 30-40° C. Chemically, olein is a glyceride of oleic acid; and, as three molecules of the acid are united to one molecule of glyceryl to form the fat, it is technically known as triolein. It is also called elain.

A limpid, colorless, highly volatile liquid, obtained by the dehydration of glycerin, or the destructive distillation of neutral fats containing glycerin. Its vapors are intensely irritating. Watts.

A red substance obtained from litmus.

A polymeric modification of acrolein obtained by heating it with caustic potash. It is a crystalline substance having an aromatic odor.

The glycerin salt of ricinoleic acid, occuring as a characteristic constituent of castor oil; -- formerly called palmin.

See Olein.

Of or containing acryl, the hypothetical radical of which acrolein is the hydride; as, acrylic acid.

A white amorphous substance obtained as a polymeric modification of acrolein.

A solid isomeric modification of olein.

Same as Olein.

Erythrolein.

ntermittent light. -- Fixed oils (Chem.), non-volatile, oily substances, as stearine and olein, which leave a permanent greasy stain, and which can not be distilled unchanged; -- distinguished from volatile or essential oils. -- Fixed pivot (Mil.), the fixed point about which any line of troops wheels. -- Fixed star…

leic acid, an acid of the acrylic acid series found combined with glyceryl in the form of olein in certain animal and vegetable fats and oils, such as sperm oil, olive oil, etc. At low temperatures the acid is crystalline, but melts to an oily liquid above 14

t), the greater portion of the solid fat, or stearin, being left behind. It is mixture of olein, palmitin, and a little stearin.

reater portion of the solid fat or stearin, by crystallization. It is mainly a mixture of olein and palmitin with some little stearin.

Ricinolein. [Obs.]

able fat, found abundantly in animals and in vegetables. It occurs mixed with stearin and olein in the fat of animal tissues, with olein and butyrin in butter, with olein in olive oil, etc. Chemically, it is a glyceride of palmitic acid, three molecules of palmitic acid being united to one molecule of glyceryl, and hen…

one of three isometric bases (C6H7N) related to pyridine, and obtained from bone oil, acrolein ammonia, and coal-tar naphtha, as colorless mobile liquids of strong odor; -- called also methyl pyridine.
