How are amine values calculated?
The amine number is determined by titration of the amine acetate ion by a dilute, typically 1N HCl solution. For pure material, the amine number can be calculated using the molecular weights of the pure compound and KOH (56.1 g/mol).
What is the molecular formula of triethylenetetramine?
Is triethylenetetramine a Tetradentate?
TETA is a tetradentate ligand in coordination chemistry, where it is referred to as trien.
How do you find the amine equivalent weight of amine?
You can determine the equivalent weight by dividing (1000*56.1) by the amine number.
What is total amine value?
The total amine value is a measure of the sample’s basicity and is defined as the number of milligrams of potas- sium hydroxide (KOH) equivalent to the basicity in 1 g of sample.
What is the amine number?
n. The number of milligrams of potassium hydroxide equivalent to the fatty amine basicity in 1 g of sample. Syn: amine equivalent.
Is triethylenetetramine a VOC?
VOC content : 1.78 lbs/gal (213.8 g/l) LogKow : -2.65 Water solubility (g/l) : The product is stable.
What is triethylenetetramine used for?
Triethylenetetramine is a copper chelating agent used for the management of Wilson’s disease in cases where penicillamine therapy is clinically inappropriate. Triethylenetatramine (TETA) is a highly selective divalent Cu(II) chelator and orphan drug that revereses copper overload in tissues.
How is epoxy amine ratio calculated?
- Calculation of Stoichiometric Ratios.
- 1 To calculate the Amine H equivalent.
- Equation 1. Amine H eq wt = MW of amine.
- 2 To calculate the stoichiometric ratio of.
- Equation 2. phr1 of amine = Amine H eq wt x 100.
- 3 Frequently, epoxy resins are blended,
- Equation 3. EEW of mix =
- Epoxy Novolac Resins. Brominated Resins.
What is amine weight?
An amine hardener has reactive N-H groups than can react with an epoxy group. The equivalent weight of an amine may be expressed as having an amine equivalent weight 30g/eq. This means that 30 g of material has one N-H group or that 60 g has 2 N-H groups or that 90 g has 3 N-H groups.
Is ammonia a primary amine?
In the gas phase, amines exhibit the basicities predicted from the electron-releasing effects of the organic substituents. Thus tertiary amines are more basic than secondary amines, which are more basic than primary amines, and finally ammonia is least basic.
What are the uses of triethylenetetramine?
Triethylenetetramine (TETA), a CuII-selective chelator and an orphan drug, is commonly used for the treatment of Wilson’s disease (1). Recently, its potential uses in cancer chemotherapy and other diseases are under investigation.
What is the formula for triethylenetetramine ( Inn ) in Wikipedia?
From Wikipedia, the free encyclopedia Triethylenetetramine (TETA and trien), also called trientine (INN), is an organic compound with the formula [CH 2 NHCH 2 CH 2 NH 2] 2. This oily liquid is colorless but, like many amines, older samples assume a yellowish color due to impurities resulting from air-oxidation. It is soluble in polar solvents.
Why does triethylenetetramine have a yellowish color?
Triethylenetetramine, abbreviated TETA and trien and also called trientine (INN), is an organic compound with the formula [CH2NHCH2CH2NH2]2. This oily liquid is colorless but, like many amines, assumes a yellowish color due to impurities resulting from air-oxidation.
What is the molecular weight of ethyleneamine E-100?
E-100 is a complex mixture of various linear, cyclic, and branched products with a number-average molecular weight of 250-300 g/mole. 2.6 Aminoethylpiperazine (AEP) Aminoethylpiperazine (CAS #000140-31-8, 1-piperazineethaneamine) is a cyclic ethyleneamine. It contains one primary, one secondary, and one tertiary amine.
What kind of base is used for triethylenetetramine?
A condensate of a poly (amine), such as diethylene triamine, triethylenetetramine, or amino ethylethanolamine, with C21 or C 22 carbon fatty acids or tall oil fatty acids can be used as corrosion inhibitor base [ 84 ]. Propargyl alcohol has been found to enhance the anticorrosive effects of the composition.
