58446-52-9 Usage
Description
Stearyl Benzoylmethane has high transmittance, non-toxic and tasteless; and solid or liquid calcium / zinc, barium / zinc and other heat stabilizer and can greatlyimprove the initial coloring of PVC, transparency, long-term stability, and processing In the precipitation and “zinc burning” and so on; it ischaracterized by zinc soap has a good synergistic effect, the formula added to the product can effectively inhibit the “zinc burn”, suitable for hard, non-toxic, odorless areas of implementation, promote calcium / Zinc composite stabilizer replacement, widely used in medical, food packaging and other non-toxic transparent PVC products (such as PVC bottles, sheet, transparent film, etc.).
Uses
Stearoyl benzoyl methane can greatly improve initial coloring performance of PVC, transparency, and long-term stability if it is used with solid or liquid calcium/zinc, barium/zinc and other heat stabilizers. It is widely used in non-toxic and transparent PVC products such as pharmaceutical and food packages.
storage
Stearoylbenzoylmethane can store in a cool dry place, to prevent moisture, heat. Do not damage the packaging when handling.
Check Digit Verification of cas no
The CAS Registry Mumber 58446-52-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,8,4,4 and 6 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 58446-52:
(7*5)+(6*8)+(5*4)+(4*4)+(3*6)+(2*5)+(1*2)=149
149 % 10 = 9
So 58446-52-9 is a valid CAS Registry Number.

METHOD FOR SYNTHESIZING BETA-DICARBONYL COMPOUNDS
-
Paragraph 0125; 0126; 0127; 0128; 0129, (2014/04/03)
A method for synthesizing beta-dicarbonyl compounds, particularly beta-diketones, from at least two carbonyl compounds, such as esters and ketones, in the presence of a strong base or a mixture of strong bases by Claisen condensation with a titer of greater than 95%. The method includes providing a synthesis reactor on which a separation column, provided with a condenser and with at least one microwave generator, is mounted; feeding a first carbonyl compound and the strong base into the synthesis reactor; heating the reactor and starting up the condenser; starting up the microwave generator(s); when the mixture is brought to a boil at total flux, feeding the second carbonyl compound into the reactor; and after a waiting time, stopping the reactor and acidifying and washing the reaction mixture.)
Process for the preparation of aromatic beta-diketones
-
, (2008/06/13)
A process is disclosed for the preparation of aromatic beta-diketones by the reaction of an acetophenone and a molar excess of an aliphatic ester or an ester of benzoic acid in the presence of sodium alkoxide condensation agent in an aromatic hydrocarbon solvent at a temperature in the range 120-170oC. The solvent and excess ester reactant may be recycled after separation of the aromatic beta-diketone product.
