The same analytical method was used as for the analysis of standard acetic acid reaction
and it was seen that under the same conditions the acetic acid peak was observed at the same location (Fig 2).
Even if the content of sulphide minerals in coal is quite small, this kind of mineral could be the origin of insoluble precipitate of acid reaction
, which can plug the fracture.
Assay for lipid peroxides in animal tissues by thiobarbituric acid reaction
The efficiency of Thiobarbituric acid reaction
of with the benzaldehyde derivative (Table 5, rows 1-7) was much better than that of thiosulfate thiobarbituric acid and dimethyl thiobarbituric acid (Table 5, No.
MDA was estimated by thiobarbituric acid reaction
(Mahalouz et al) by manual method.
Lipid peroxidation in injured brain tissue was estimated by the thiobarbituric acid reaction
method for MDA described by Ohkawa et al.
14) Further evidence of cellulose half-acid ester products, as a result of aqueous malcamic acid reaction
with cellulose, has been reported by Cuculo (12) and in Ford et al.
Because of the autocatalytic effect of acid and high concentration of MA in the liquid phase at the beginning of the reaction, the carboxylic acid reaction
rate is very steep at the beginning of the reaction.
Just as the ball loses energy to the pillow, a sound wave loses energy to the borate-to-boric acid reaction

and the autoxidations of polyunsaturated fatty acid methyl esters.
Workers have to go into acid reaction
chambers filled with toxic fumes and scour scale from filters and walls.
The acetylsalicylic acid reaction
triad of bronchospasm, rhinitis / sinusitis, and nasal polyposis is often accompanied by rash and gastrointestinal distress.
