Metal corrosion inhibitor and hydrogen chloride formation inhibitor in a crude oil atmospheric distillation unit

The quaternary ammonium compound described by general formula 1 below (wherein R1, R2 and R3 are the same or different hydrocarbon radicals with 1 to 4 carbon atoms, and n is an integer between 1 and 10) is used as a metal corrosion inhibitor. With this metal corrosion inhibitor, it is possible even with the addition of small quantities to adequately prevent corrosion of metal in a steam generating unit or petroleum refining or petrochemical process unit. Moreover, (β-hydroxyethyl)trimethylammonium hydroxide is used as a hydrogen chloride formation inhibitor for a crude oil atmospheric distillation unit. With this hydrogen chloride formation inhibitor, it is possible to prevent the formation of hydrogen chloride itself in a crude oil atmospheric distillation unit without having any adverse effect on the catalyst.

Bone marrow on x chromosome kinase (BMX) inhibitors and uses thereof

ActiveUS20150246913A1Amplify tyrosine kinase signalingDownstream signaling can be enhancedBiocideOrganic chemistryDiseaseTec kinase
The present invention provides novel compounds of Formula (I), and pharmaceutically acceptable salts, solvates, hydrates, polymorphs, co-crystals, tautomers, stereoisomers, isotopically labeled derivatives, prodrugs, and compositions thereof. Also provided are methods and kits involving the compounds of Formula (I) or (II), or compositions thereof, for treating or preventing a wide range of diseases (e.g., proliferative diseases (e.g., cancers, benign neoplasms, angiogenesis, inflammatory diseases, autoimmune diseases) and metabolic diseases (e.g., diabetes (e.g., type 2 diabetes, gestational diabetes)) in a subject. Treatment of a subject with a disease using a compound of Formula (I) or (II), or compositions thereof, may downregulate the expression and / or inhibit the activity of a kinase (e.g., a tyrosine kinase, such as a Tec kinase, in particular, bone marrow on X chromosome kinase (BMX)), and therefore, suppress tyrosine kinase singling in the subject.

Air/fuel ratio control device for internal combustion engine

An air-fuel ratio control apparatus for an internal combustion engine, implementing integral correction of the air-fuel ratio by an integral term edfii obtained by multiplying an integrated difference between a target air fuel ratio and the actual air-fuel ratio by an integral gain, wherein the upper and lower limit values of the integral term are set based on the actual intake air amount and the actual air-fuel ratio. This limits the range of the integral term edfii to prevent it from being set at an excessively high or low level removed from the realities of the intake air amount and the air-fuel ratio, and thereby to prevent erroneous air-fuel ratio correction by the integral term.
