General Description

2-Amino-2-propanol, also known as diisopropanolamine (DIPA), is an organic compound with the chemical formula C6H15NO. It is a colorless, viscous liquid with an ammonia-like odor, and it is soluble in water and alcohol. 2-Amino-2-propanol has a variety of applications, including its use as a corrosion inhibitor, surfactant, and in the production of pharmaceuticals, agrochemicals, and cosmetics. It can also be used in the synthesis of other organic compounds. Additionally, due to its ability to act as a weak base, 2-amino-2-propanol is used in the manufacturing of epoxy resin hardeners and in the production of polyurethane foam. While it has various industrial applications, 2-amino-2-propanol should be handled with care and used in a well-ventilated area due to its potential irritant properties.

The invention relates to a propylene glycol and liquid ammonia as raw materials for preparing propylene diamine method and apparatus thereof

The invention relates to a method for preparing propane diamine by taking propylene glycol and liquid ammonia as raw materials. Propylene glycol and liquid ammonia are mixed in a certain ratio and are pumped into a reactor by virtue of a pump, and reaction is carried out in presence of a catalyst and hydrogen. The method for preparing the propane diamine by taking the propylene glycol and liquid ammonia as the raw materials has the advantages that a novel catalyst is adopted, catalytic performance is excellent, and long-time operation can be easily carried out; propylene glycol is subjected to hydroamination for producing a propane diamine product at lower reaction pressure, and reaction conditions are adjusted and changed, so that composition of the product can be flexibly adjusted and changed, selectivity of a target product is improved, a reaction process is simple, one-time investment of a production unit and production cost are reduced, a reaction product and a catalyst can be simply separated, and large-scale continuous industrial production can be easily realized.

Process for producing alkanolamines

A process for producing an alkanolamine includes supplying a reactive distillation apparatus having an inner contacting surface which simultaneously facilitates a reaction process and a distillation process, feeding a first reactant including an amine represented by R′3-XNHX, wherein R′ is a hydrocarbon group, and X is 1, 2, or 3, feeding a second reactant including an akylene oxide represented by R″O, wherein R″ is a C2-C10-alkylene, feeding a catalyst in an amount from 0% to about 15% by weight of a mixture of the first reactant, the second reactant and the catalyst; recycling an overhead output from an overhead portion including an unreacted portion of the amine and the catalyst to achieve a substantially total reflux of the amine and the catalyst, and collecting a product output including an alkanolamine, the alkanolamine being a member selected from the group consisting of a monoalkanolamine, a dialkanolamine, and a trialkanolamine.

Composition for preventing lactation or pregnancy in mammals and the method for using the same

α-D-6-methylergolinyl-8-acetamides of the formula: SPC1 Are readily prepared from α-D-6-methylergolinyl-8-acetic acid azide hydrochloride and amines of the formula R1 -NH-R2 and may be converted to their salts with inorganic and organic acids by neutralization. In these formulas, R1 may be hydrogen or lower alkyl, R2 may be hydrogen, lower alkyl, cycloalkyl having 5 or 6 carbon atoms, hydroxyalkyl having 3 or 4 carbon atoms, or lower alkoxycarbonylmethyl or R1 and R2 jointly may be divalent alkylene having 4 or 5 C atoms. The salts of most of these bases with physiologically tolerated acids are nontoxic in doses which suppress lactatical and prevent pregnancy in rats when applied orally after copulation. The others, equally non-toxic, extend the effective period of thiopental.
