DEF

A 98% pure form of acetic acid used in production of acetate fiber.

CONT

Glacial acetic acid is [a] pure compound [99.8% min.], as distinguished from the usual water solutions known as acetic acid, [which] crystallizes at 62°F.

CONT

Acetic acid is the most extensively used organic acid, and is obtained either by the oxidation of alcohol and aldehyde, or by the destructive distillation of wood and carbohydrates in general. This yields an impure pyroligneous vinegar, which is subsequently purified. ... Stahl proposed in 1700 a method to obtain acetic acid from vinegar by exposing the latter substance to a freezing temperature, separating the ice from the stronger acid; another method he suggested was to neutralize with an alkali and to evaporate, then distilling with an equal amount of sulphuric acid. In 1759 Count de Lauraguais obtained a crystallized acetic acid in a distillate of cuprum acetate, then known as "copper spirit." The name glacial acetic acid was affixed to this substance by Löwitz (1793), who repeatedly distilled diluted acetic acid with powdered charcoal, and obtained thereby a crystalline acid by subjecting the product to a low temperature.

OBS

In the context of spotting, glacial acetic must be diluted to a 5-7% concentration. Glacial acetic is extremely hazardous (toxic fumes, severe skin burns) and should not be used without special training, personal protective equipment (PPE), and under carefully controlled conditions.

OBS

glacial: glass-like, crystallized. This usage persists in terms such as glacial acetic acid and glacial phosphoric acid.

DEF

A chemical compound having the formula C5H9NO4 or HOCO-(CH2)2-CHNH2-COOH which appears under the form of a white, odorless, crystalline powder, is slightly soluble in cold water, is insoluble in organic solvents, constitutes a non-essential amino acid, and is used as a salt substitute and to improve the taste of beer.

CONT

The truth of the matter is that the glutamic acid found in unprocessed, unadulterated food and in the human body is composed of one form of a single amino acid, L-glutamic acid, and nothing else. In contrast, the processed free glutamic acid used in processed food is always composed of two forms of glutamic acid (L-glutamic acid and D-glutamic acid) and a variety of other chemicals commonly referred to as contaminants.
