21291-99-6 Usage
General Description
1,2,3-Propanetriamine, also known as diethylenetriamine or DETA, is an organic compound with the formula HN(CH2CH2NH2)2. This colorless liquid is a strong base and is often found in industrial products, scientific research, and chemical production due to its polyfunctional properties. It’s used in the production of chelating agents, lubricant additives, adhesives, and epoxy curing agents amongst other things. DETA can cause irritation to skin and eyes, and prolonged exposure can be harmful, so it should be handled with appropriate safety measures. It can also act as a building block in the production of various other chemical compounds.
Check Digit Verification of cas no
The CAS Registry Mumber 21291-99-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,2,9 and 1 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 21291-99:
(7*2)+(6*1)+(5*2)+(4*9)+(3*1)+(2*9)+(1*9)=96
96 % 10 = 6
So 21291-99-6 is a valid CAS Registry Number.

METHOD FOR PRODUCING AMINES FROM GLYCERIN
-
Page/Page column 12-13; 14, (2010/10/03)
The present invention relates to a process for preparing amines by reacting glycerol with hydrogen and an aminating agent from the group of ammonia and primary and secondary amines in the presence of a catalyst at a temperature of from 100° C. to 400° C. and a pressure of from 0.01 to 40 MPa (from 0.1 to 400 bar). Preference is given to using glycerol based on renewable raw materials. The catalyst preferably comprises one metal or a plurality of metals or one or more oxygen compounds of the metals of groups 8 and/or 9 and/or 10 and/or 11 of the Periodic Table of the Elements. The invention further relates to the use of the reaction products as an additive in cement or concrete production and in other fields of use. This invention further provides the compounds 1,2,3-triaminopropane, 2-aminomethyl-6-methylpiperazine, 2,5-bis(aminomethyl)piperazine and 2,6-bis(aminomethyl)piperazine.
