138 results about "Araboascorbic Acid" patented technology

Erythorbic acid (isoascorbic acid, D-araboascorbic acid, (D-)erythroascorbic acid) is a stereoisomer of ascorbic acid (vitamin C). It is synthesized by a reaction between methyl 2-keto-D-gluconate and sodium methoxide.

Diverting acid for carrying out acidification and transformation on high-temperature oil and gas well with long well segment

The invention relates to diverting acid for carrying out acidification and transformation on a high-temperature oil and gas well with a long well segment, which comprises the following components: 4.5 to 5.0 percent by mass of diverter octadecanoyl amido ethyl dimethylamine betaine, 1.0 to 2.0 percent by mass of corrosion inhibitor Mannich base, 1.0 to 2.0 percent by mass of ferric ion stabilizererythorbic acid or sodium erythorbate, 20 percent by mass of hydrochloric acid and the balance water. According to the invention, the characteristic that the diverting acid has different molecule aggregation morphologies and aggregation numbers under different pH values is utilized; the high temperature resistance diverting acid with viscoelasticity is prepared by adding the corrosion inhibitor Mannich base and the ferric ion stabilizer erythorbic acid or sodium erythorbate; and after the diverting acid is injected into a formation, the viscosity of the acid is rapidly improved along with theconsumption of the acid and the injection pressure at the bottom of the well also rises along with the consumption of the acid, so that the acid is forced to permeate and divert toward the formation,a reservoir is uniformly acidified and the acidification effect is obviously improved.
