The decomposition of methionine in sulfuric acid.
The classical procedure for the preparation of homocystine consists of boiling a solution of methionine in 50 per cent sulfuric acid followed by neutralization (1). Although the yields of homocystine account for only 25 to 45 per cent of the methionine, the nature of the reaction has received little attention since originally published by Butz and du Vigneaud (1). These authors noted the format...
متن کاملDetermination of ultra trace amount Chromium in water samples with the 1-(2-PyridylAzo)-2-Naphthol, (PAN) by the bromate ion in sulfuric acid with kinetic spectrophotometric method
A new kinetic spectrophotometic method for the determination of trace amount Chromium (III) in Teareal samples has been described based on it s the catalytic effect on the oxidations of 1 - ( 2 –PyridylAzo ) - 2 - Naphthol, (PAN), by potassium bromated in sulfuric acid. The reaction is followedspec- trophotometrically by measuring the decrease in the absorbance at 469 nm. Under the optimumcondi...
متن کاملMetal Components (Fe, Al, and Ti) Recovery from Red Mud by Sulfuric Acid Leaching Assisted with Ultrasonic Waves
Abstract—Nowadays the red mud generated from Bayer alumina production process seriously threats the environment and human safety. Therefore, reduction and recycling of red mud is an urgent topic in aluminum industry. In this study, the effects of various parameters, ultrasound power, reaction temperature, leaching time, acid concentration, and solid to liquid ratio on the leaching of Fe, Al, an...
متن کاملA Comparative Study of Aluminium Alloy and Titanium Alloy Comparison of AL-7175 alloy and Ti6Al4V alloy (Literature Survey Paper)
About 50% of metals used in Aerospace industries are Aluminium and Titanium alloys, Alloys such as Ti6Al4V, AL-7175, and AL7075 are used extensively in space vehicles, aviation, and automotive industries for having enhanced mechanical properties like High strength to weight ratio, low Thermal Expansion and better Corrosion resistance. Comparison of properties Aluminium and Titanium alloys shows...
