mixed acid

This mixture is sometimes called "mixed acid."

Mix the two acids together, and cool the mixed acids to 10 degrees centigrade.

Acylation of the 1-sn-lysophosphatide provides a convenient method for preparation of mixed acid 1-sn-phosphatidylcholines which are not otherwise available.

Key words: lipid–protein interactions, adaptation, mixed acid lipids.

The term is also used to refer to mixed acid compounds used in metalworking processes, especially etching.

This active ingredient, which can be isolated in the case of nitronium tetrafluoroborate, also effects nitration without the need for the mixed acid.

Add glycerine until there is a thin layer of glycerine on top of the mixed acids.

The band were part of the Madchester movement, a style of alternative rock that mixed acid house rhythms with guitar pop sounds.

Thus, the glycerin mixture is added slowly to the reaction vessel containing the mixed acid (not acid to glycerin).

P. vulgaris also tests positive for the methyl red (mixed acid fermentation) test and is also an extremely motile organism.

The methyl red test detects production of acids formed during metabolism using mixed acid fermentation pathway using pyruvate as a substrate.

Typical nitration syntheses apply so-called "mixed acid", a mixture of concentrated nitric acid and sulfuric acids.

Nitrobenzene is prepared by nitration of benzene with a mixture of concentrated sulfuric acid, water, and nitric acid, called "mixed acid."

Numerous fermentation pathways exist e.g. lactic acid fermentation, mixed acid fermentation, 2-3 butanediol fermentation.

Some enterics subsequently use the mixed acid pathway to metabolize pyruvic acid to other acids, such as lactic, acetic, and formic acids.

As an example of mixed acid fermentation, bacteria such as Clostridium pasteurianum ferment glucose producing butyrate, acetate, carbon dioxide and hydrogen gas:

Principle: It is used to determine the ability of an organism to produce mixed acids by fermentation of glucose and to overcome the buffering capacity of the medium.

In a related reaction, sulfuric acid gives nitrosylsulfuric acid, the mixed acid anhydride of nitrous and sulfuric acid:

The higher yields of the twofold ipso-nitration product anti-7 were obtained in nitration of anti-4 with fuming nitric acid or mixed acid (HNO3–H2SO4).

Methanoyl fluoride undergoes the reactions expected of an acyl halide: alcohols and carboxylic acids are converted to methanoate esters and mixed acid anhydrides, respectively.

The pH indicator Methyl Red is added to one tube and a red color appears at pH's lower than 4.2, indicating a positive test (mixed acid fermentation is used).

The Delta Ratio is a formula that can be used to assess elevated anion gap metabolic acidosis and to evaluate whether mixed acid base disorder (metabolic acidosis) is present.

Research on mixed acids continues and it has been shown that low concentrations of hydrochloric acid can improve the electrochemical response of the cerium reaction, while nitric acid additions had negative results.

If propionic acid, butyric acid and longer monocarboxylic acids are produced (see mixed acid fermentation), the amount of acidity produced per glucose consumed will decrease, as with ethanol, allowing faster growth.

The formation of the mixed acid can be due either to the direct interaction of the two acids or to the decomposition of the metatungstic acid, substituted by the molybdenum, which would be formed transiently.
