A novel anion exchange polymer is provided. A method of making the anion exchange polymer includes reacting a tertiary amine, an acid inhibitor and a polyepoxide to form a quaternary ammonium monomer and polymerizing the quaternary ammonium monomer in the presence of a catalyst. The exchange polymer is prepared without using alkyl halides and can be used to make improved ion exchange materials that are chemically resistant and non-fouling.

A corrosion control system is disclosed including an anionic oxygen inhibitor, a cationic acid inhibitor or dispersant, and a noxious species inhibitor or scavenger for use in a fluid in contact with a metallic surface at low temperature, moderate temperature and especially at high temperature. A drilling fluid, a completion fluid, a production fluid and a geothermal fluid including an effective amount of the corrosion control system is also disclosed as well as methods for making and using same.

An acid inhibitor concentrate is provided which contains water, at least one polyamino-aldehyde resin such as a quaternized polyethylenepolyamine-glyoxal resin, and at least one compound selected from the group consisting of acetylenic alcohols, ethoxylated fatty amines, ethoxylated fatty amine salts, and aldehyde-releasing compounds (such as hexamethylenetetramine). Such concentrates form useful metal cleaning and pickling solutions when combined with aqueous acid, wherein such solutions, when contacted with a metal surface, are effective in removing scale, smut and other deposits from the metal surface but exhibit a reduced tendency for the aqueous acid to attack or etch the metal itself.

The invention discloses a new fertilizer dosage form-foliar fertilizer effervescent tablet and a method for preparing the same. The foliar fertilizer effervescent tablet of the invention is characterized by drying, grinding and sieving the foliar fertilizer or a plant nutrient solution raw powder, an acid inhibitor, a carbon dioxide agent and a surfactant, mixing uniformly, pressing the mixture in a tabletting machine to get the finished product after wetting the mixture by a wetting adhesive. The foliar fertilizer can automatically disintegrate into the plant nutrient solution for foliar spray after the foliar fertilizer is added into the water, and is tend to quantitative use.

The invention provides an acid inhibitor, which includes dormison, triethanolamine, phosphoric acid, antimony oxide, the synergistic agent and the soluble solvent. The inhibitor has improved the effect and decreased the cost; it can be used to the all kinds of the acid and major in the oil well acidification.

The present disclosure provides enteric coated capsules and orally dissolving films comprising non-steroidal anti-inflammatory drugs and acid inhibitors, as well as methods of treating treatment humans for pain and / or inflammation while reducing gastrointestinal side effects.

The present disclosure is directed to a method for treating a disease or disorder in a patient at risk of developing an NSAID-associated ulcer by administering to the patient in need thereof a pharmaceutical composition in unit dosage form comprising aspirin, or a pharmaceutically acceptable salt thereof, and an acid inhibitor to the at risk patient and thereby decreasing the patient's risk of developing an ulcer.

The invention relates to a cleaning device for cleaning a boiler, belonging to the technical field of chemical cleaning of equipment. The cleaning device comprises a cleaning circulating pump (1), a cleaning solution disposing box (2), a water injection pump (3) and a water supply tank (4); the cleaning circulating pump (1), the cleaning solution disposing box (2) and a boiler system (6) are connected into a cleaning solution circulating loop through a pipeline; the cleaning solution disposing box (2) is a stainless steel sealing container; and a plurality of ultrasonic transducers (11) are uniformly distributed on the outer surface of the paraboloid of the container. The cleaning device is convenient to operate and control, avoids being damaged by dismounting for cleaning due to no need of dismounting a heat exchange element of the boiler during cleaning operation, remarkably reduces maintenance cost and risks of equipment, also increases the utilization ratio of an acid inhibitor by40%, reduces the consumption of chemical agents and has rather considerable economic and environment-friendly benefits.

The present invention discloses one kind of quantitative detecting reagent for neutral alpha-glucosidase in seminal plasma. The detecting reagent includes acid inhibitor, glycosidase inhibitor, quality controlling liquid, substrate, substrate dissolving liquid, terminating liquid, and standard sample. Compounding the substrate can raise the reaction speed greatly, and compounding and detecting the quality controlling liquid can monitor the operation process accurately. The present invention also discloses the reagent kit with the quantitative detecting reagent for neutral alpha-glucosidase in seminal plasma and the preparation process of the detecting reagent.

The present invention relates to a stratum opener agent which is applied to oilfield low permeability reservoir. The stratum opener agent comprises two parts: pre-disposal liquid and acid inhibitor system; according to the weight percentage, the pre-disposal liquid consists of solvent and surfactant as follows: 1-3% of organic solvent such as higher alcohol, 0.2-1% of non-ionized surfactant polyoxyethylene alkylolamide, 0.3-0.5% of pentadecane alkyl sulfonate, and the residual quantity of stratum water; according to the weight percentage, the acid inhibitor system comprises 5-10% of low-carbon organic acid, 1-3% of hydrofluoric acid, 0.5% of inhibitor thio-phosphate imidazoline polyoxyethylene ether, 1% of adsorption inhibitor and the residual quantity of water; the adsorption inhibitor comprises 0.5-2% of ethyl dimethylene-bi-cetyltrimethylammonium ammonium bromide, 0.2-1% of quaternary ammonium salt small kation, 2-5% of inorganic salt, 0.2% of 1,3-amine group propyl alcohol N-methyl sodium phosphate or potassium dihydrogen phosphate or sodium hexametaphosphate. The stratum opener agent can effectively improve the seepage capability of reservoir and achieve the objects of decompression and augmented injection and improving the yielding.

The invention discloses a traditional Chinese medicinal compound colloidal bismuth pectin capsule for treating a peptic ulcer and a preparation method thereof. The traditional Chinese medicinal compound colloidal bismuth pectin capsule for treating the peptic ulcer is prepared from the following raw materials in parts by weight: 35-45 parts of colloidal bismuth pectin (metered with the weight of bismuth), 15-25 parts of an acid inhibitor, 50-150 parts of an antibacterial agent, 20-40 parts of ganoderan extracts, 8-15 parts of hydroxypropyl methyl cellulose phthalate, 25-60 parts of a disintegrating agent and 20-60 parts of an emulsifying agent, wherein the acid inhibitor is clad with permethylated-[beta]-cyclodextrin. The obtained capsule is not only good in dispersity and obvious in sustained release effect, but also improves the immunity of an organism, and has an obvious restoring function for the hypoimmunity caused by western medicinal antibiotics.

An acid inhibitor concentrate is provided which contains water, at least one polyamino-aldehyde resin such as a quaternized polyethylenepolyamine-glyoxal resin, and at least one compound selected from the group consisting of acetylenic alcohols, ethoxylated fatty amines, ethoxylated fatty amine salts, and aldehyde-releasing compounds (such as hexamethylenetetrarnine). Such concentrates form useful metal cleaning and pickling solutions when combined with aqueous acid, wherein such solutions, when contacted with a metal surface, are effective in removing scale, smut and other deposits from the metal surface but exhibit a reduced tendency for the aqueous acid to attack or etch the metal itself.
