of formula (I; SO2NH2 is SO2X) (where X = halogen), with NH3 in suitable solvent such as water; or with cpds. from which ammonia can be liberated such as ammonium salts of hexamethylenetetramine etc. (I) have diuretic and saluretic activity with very low excretion of K-ions and low...
Find the Molar Mass of Benzoic Acid, H6C7O2 Step-by-Step There are 4 easy steps to find the molar mass of H6C7O2 based on its chemical formula. 1. Count The Number of Each Atom The first step to finding the molar mass of Benzoic Acid is to count the number of each atom present ...
1. A process for preparing an ammonium salt of an aromatic carboxylic acid by reacting the aromatic carboxylic acid with ammonia in an aprotic solvent, which comprises carrying out the reaction in a closed vessel comprising a gas space by continuously introducing a solution of the aromatic carboxyl...
substd. with halogen, lower alkyl, hydroxy or lower alkoxy; Y = -O, -S or -CH2-; X = -O or H2. Prepn. is by reacting a cpd. of formula (I; SO2NH2 is SO2X) (where X = halogen), with NH3 in suitable solvent such as water; or with cpds. from which ammonia can be ...
text>Three Cu(II) coordination compounds (CCs) with 4,4'-oxybisbenzoic acid (H(2)OBBA), {Cu-3(OBBA)(2)(NH3)(4)}(n) (1), {Cu(OBBA)(0.5)(NH3)}(n) (2), {Cu-2(OBBA) (NH3) (OH)}(n) (3) were synthesized under the ammoniacal condition in mixed solvents and characterized...
Slurry pH is one of the most significant factors influencing ammonia emission, ammonia volatilisation increasing with an increasing manure pH. Buhler et al., (2006) demonstrated that dietary benzoic acid significantly lowered urinary pH in grower and finisher pigs. Therefore, the objective of the ...
(1) contacting a solution containing an amino-hydroxy-benzoic acid corresponding to the salt (I) and/or its anions in a polar solvent having a pH of 4 with a protonic acid H2A and an activated carbon at 0-200 degreesC; (2) separating the solid from the mixture; and (3) isolating ...
benzoic acid to guide the deposition location of Ru.The developed catalyst with confined RuCo alloy particles exhibits high resistance against Ru sintering and displays excellent activity and long term stability for NH3 synthesis,achieving an NH3 synthesis rate of up to 18.9 mmolNH3gcat-1th-1at ...
Formed by cyclisation of cmpds. of formula (II): in a polar amide solvent, pref. N-methylpyrrolidone, by sulphuric acid, oleum or SO3, pref. at 80-140 degrees C. The sulphuric acid used or formed in the reaction is neutralised with NH3 or ammonium, alkali or alkaline earth hydroxides...
