Methyl methacrylate (MMA) is an organic compound with the formula CH 2 =C(CH 3)COOCH 3. This colorless liquid, the methyl ester of methacrylic acid (MAA), is a ...
Reference ranges for urine tests are described below: Measurement Lower limit Upper limit Unit Urinary specific gravity: 1.003 [1] [2] 1.030 [1] [2] g/mL Urobilinogen:
The urine test strip test for specific gravity is based on the change in dissociation constant (pK a) of an anionic polyelectrolyte (poly-(methyl vinyl ether/maleic anhydride)) in an alkali medium that is ionised and releases hydrogen ions in proportion to the number of cations present in the solution.

This derivative in turn is hydrolyzed to methacrylic acid, or esterified to methyl methacrylate in one step. Another route to methacrylic acid starts with isobutylene, which obtainable by dehydration of tert-butanol. Isobutylene is oxidized sequentially to methacrolein and then methacrylic acid.
Trace levels of protein in the urine can be normal, [60] but high levels (proteinuria) can indicate kidney disease. [45] Most cases of proteinuria are caused by increased levels of albumin , [ 61 ] which test strips can detect relatively well; but they are markedly less sensitive to other proteins, such as Bence-Jones protein , [ 62 ] which may ...

Methyl acrylate can be prepared by debromination of methyl 2,3-dibromopropanoate with zinc. [10] Methyl acrylate is formed in good yield on pyrolysis of methyl lactate in the presence of ethenone (ketene). [11] Methyl lactate is a renewable "green chemical". Another patent [12] describes the dehydration of methyl lactate over zeolites.
