Tris Saturated Phenol

Supplier From China
Apr-10-21

Tris saturated phenol:

1. Take out the re steamed phenol from the refrigerator and place it in a 68 water bath at room temperature to dissolve it. Do not put it in a 68 â?? water bath immediately to prevent the glass from cracking;

2. Add 8-hydroxyquinoline to 0.1% and �² - mercaptoethanol to 0.2% (stock solution 14.4mol/ml), mix well, the solution turns yellow, and pour into the separating funnel (it can also be carried out in a beaker);

3. Add 1mol / ml tris (ph8.0) of the same solvent, mix it repeatedly, and let it stand still until it is layered; release the Yellow phenol solution in the lower layer and discard the upper layer;

4. Add solid Tris about 1g / 100ml phenol, shake well and remove the aqueous phase;

5. Add 0.1mol/mltris (ph8.0) to balance several times until pH is 8.0;

6. Add 0.1mol/mltris (ph8.0) and store in brown bottle for 4 degrees;

7. If yellow disappears or pink, it cannot be used.

Tris saturated phenol is toxic and has a strong irritant effect on skin and human body, so it needs to be operated in the fume hood. Avoid harm, safety first.

Hexahydro-1,3,5-Tris(Hydroxyethyl)-S-Triazine

$10
MOQ: 1  Kilograms
Sample Available
 
Hexahydro-1,3,5-Tris(hydroxyethyl)-S-Triazine is a triazine derivative contained in cutting fluids. It is a formaldehyde releaser. Hexahydro-1,3,5-tris(hydroxyethyl)-s-triazine is an amine and an alcohol. Amines are chemical bases. They neutralize acids to form salts plus water. These acid-base reactions are exothermic. The amount of heat that is evolved per mole of amine in a neutralization is largely independent of the strength of the amine as a base. Amines may be incompatible with isocyanates, halogenated organics, peroxides, phenols (acidic), epoxides, anhydrides, and acid halides. Flammable gaseous hydrogen is generated by amines in combination with strong reducing agents, such as hydrides.
Hexahydro-l,3,5-tris-(2-hydroxyethyl)triazin is used in organic synthesis; as a bactericide in cooling fluids and various cosmetic products; formaldehyde liberator. Hexahydro-1,3,5-tris(hydroxyethyl)-s-triazine is probably combustible. It is a triazine derivative contained as a bio cide in cutting fluids. It is a formaldehyde releaser. Dermatitis, delayed-type allergic conjunctivitis, and asthma were described.

Supplier From North York, Ontario, Canada
 
CAS 108-94-1

HS code 2914220000

Cyclohexanone is an organic compound with the chemical formula C6H10O. It is a saturated cycloketone with carbonyl carbon atoms included in the six-membered ring. Colorless transparent liquid, with an earthy smell, containing traces of phenol, with a mint smell. Impurity for light yellow, with storage time generated impurities and color, water white to gray yellow, with a strong pungent smell. Mixed with air, the explosive pole is identical to the open-chain saturated ketone. In industry, it is mainly used as raw material and solvent for organic synthesis, such as it can dissolve cellulose nitrate, paint, paint and so on.

Cyclohexanone is an important chemical raw material, which is the main intermediate in the manufacture of nylon, caprolactam and adipic acid. They are also important industrial solvents, such as paints, especially those containing nitrocellulose, vinyl chloride polymers and their copolymers or methacrylate polymers. Excellent solvent for organophosphorus insecticides and many similar pesticides, as a solvent for dyes, as a viscous solvent for piston-type aviation lubricating oil, as a solvent for grease, wax and rubber. It is also used as a homogenizing agent for dyeing and fading filaments, as a degreaser for polishing metals, and as a coloring and painting agent for wood. Used as a high boiling solvent in cosmetics such as nail polish. Mixed solvent is usually prepared with low boiling solvent and medium boiling solvent to obtain suitable evaporation rate and viscosity.
