1116-76-3 Usage

Chemical Properties

Tri-n-octylamine is clear colorless liquid

Uses

Different sources of media describe the Uses of 1116-76-3 differently. You can refer to the following data:
1. Tri-n-octylamine is used as an extractant for organic acids and precious metals.
2. Tri-n-octylamine is used as an extractant for organic acids like trichloroacetic acid, succinic acid, acetic acid and precious metals. It is also used as a solvent and an intermediate in the manufacture of pharmaceuticals. Further, it is employed in the preparation of quaternary ammonium compounds, agrochemicals, surfactants, lubricant additives, corrosion inhibitors, vulcanization accelerators and dyes.
3. Trioctylamine is used as an extractant for organic acids (such as TCA, succinic acid, and acetic acid), and precious metals.

Purification Methods

It is converted to the amine hydrochloride etherate which is recrystallised four times from diethyl ether at -30o (see below). Neutralisation of this salt regenerates the free amine which distil under high vacuum. [Wilson & Wogman J Phys Chem 66 1552 1962.] Distil the amine at 1-2mm pressure. [Beilstein 4 H 196, 4 III 382, 4 IV 754.]

Check Digit Verification of cas no

The CAS Registry Mumber 1116-76-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,1,1 and 6 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1116-76:
(6*1)+(5*1)+(4*1)+(3*6)+(2*7)+(1*6)=53
53 % 10 = 3
So 1116-76-3 is a valid CAS Registry Number.

A multifaceted role of a mobile bismuth promoter in alcohol amination over cobalt catalysts

Bahri, Mounib,Ersen, Ovidiu,Khodakov, Andrei Y.,Kusema, Bright T.,Niu, Feng,Ordomsky, Vitaly V.,Yan, Zhen

, p. 4270 - 4278 (2020)

Promotion with small amounts of different elements is an efficient strategy for the enhancement of the performance of many heterogeneous catalysts. Supported cobalt catalysts exhibit significant activity in the synthesis of primary amines via alcohol amination with ammonia, which is an economically efficient and environmentally friendly process. Insufficient selectivity to primary amines, low activity and fast cobalt catalyst deactivation remain serious issues restricting the application of alcohol amination in the industry. In this work, we have discovered the multifaceted role of the bismuth promoter, which is highly mobile under reaction conditions, in 1-octanol amination over supported cobalt catalysts. First, the overall reaction rate was enhanced more than twice on promotion with bismuth. Second, the selectivity to primary amines increased 6 times in the presence of Bi at high alcohol conversion. Finally, the bismuth promotion resulted in extremely high stability of the cobalt catalyst. Characterization by XRD, temperature programmed reduction, STEM, CO chemisorption, BET, TGA and FTIR has showed that the enhancement of the catalytic performance on promotion with bismuth is due to better cobalt reducibility, easy removal of strongly adsorbed intermediates and products by the mobile promoter and suppression of amine coupling reactions resulting in secondary and tertiary amines.

Catalytic amination of octanol for synthesis of trioctylamine and catalyst characterization

Li, Yunling,Li, Qiuxiao,Zhi, Lifei,Zhang, Minghui

, p. 1635 - 1642 (2011)

Synthesis of trioctylamine by the amination of octanol and ammonia under atmospheric pressure over an excellent Ni-Cu catalyst supported on diatomite is studied in this article. The key factor for the synthesis is the preparation of catalyst with a high activity and selectivity. The activity and selectivity can be adjusted by varying the Ni to Cu ratios. The optimum molar ratio of Ni to Cu was 1.25:1. For the catalyst with a Ni/Cu ratio of 1.25:1, the conversion of octanol and the selectivity of trioctylamine reached 100 and 97.3%, respectively, at 5 h. The reaction of dioctylamine with octanol was the rate-determining step for the formation of trioctylamine. The Physical properties of catalysts, such as particle size, Brunauer-Emmett-Teller (BET) surface area, valence state of catalyst elements, morphology and reduction properties of catalysts were investigated by using X-ray diffraction, nitrogen adsorption-desorption isotherms (BET), X-ray photoelectron spectroscopy, Transmission electron microscopy, and temperature programmed reduction, respectively. The reaction scheme of catalytic amination of octanol with ammonia was discussed. Graphical Abstract: [Figure not available: see fulltext.][Figure not available: see fulltext.]

Highly Selective Hydrogenative Conversion of Nitriles into Tertiary, Secondary, and Primary Amines under Flow Reaction Conditions

Furugen, Chikara,Ito, Naoya,Jiang, Jing,Park, Kwihwan,Sajiki, Hironao,Shimizu, Eisho,Yamada, Tsuyoshi

, (2021/12/13)

Flow reaction methods have been developed to selectively synthesize tertiary, secondary, and primary amines depending on heterogeneous platinum-group metal species under catalytic hydrogenation conditions using nitriles as starting materials. A 10 % Pd/C-packed catalyst cartridge affords symmetrically substituted tertiary amines in good to excellent yields. A 10 % Rh/C-packed catalyst cartridge enables the divergent synthesis of secondary and primary amines, with either cyclohexane or acetic acid as a solvent, respectively. Reaction parameters, such as the metal catalyst, solvent, and reaction temperature, and continuous-flow conditions, such as flow direction and second support of the catalyst in a catalyst cartridge, are quite important for controlling the reaction between the hydrogenation of nitriles and nucleophilic attack of in situ-generated amines to imine intermediates. A wide variety of aliphatic and aromatic nitriles could be highly selectively transformed into the corresponding tertiary, secondary, and primary amines by simply changing the metal species of the catalyst or flow parameters. Furthermore, the selective continuous-flow methodologies are applied over at least 72 h to afford three different types of amines in 80–99 % yield without decrease in catalytic activities.

Conversion of Primary Amines to Symmetrical Secondary and Tertiary Amines using a Co-Rh Heterobimetallic Nanocatalyst

Chung, Hyunho,Han, Seulgi,Chung, Young Keun,Park, Ji Hoon

supporting information, p. 1267 - 1272 (2018/02/12)

Symmetrical tertiary amines have been efficiently realized from amine and secondary amines via deaminated homocoupling with heterogeneous bimetallic Co2Rh2/C as catalyst (molar ratio Co:Rh=2:2). Unsymmetric secondary anilines were produced from the reaction of anilines with symmetric tertiary amines. The Co2Rh2/C catalyst exhibited very high catalytic activity towards a wide range of amines and could be conveniently recycled ten times without considerable leaching. (Figure presented.).
