Flammability and Explosibility


Check Digit Verification of cas no

The CAS Registry Mumber 82799-44-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,2,7,9 and 9 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 82799-44:
178 % 10 = 8
So 82799-44-8 is a valid CAS Registry Number.

, (2021/02/01)

A mild and efficient system has been discovered for the synthesis of α-aryl carbonyl compounds via oxidation of benzylic C–H to C[dbnd]O bonds. This ultraviolet-light-mediated oxygenation reaction exhibited excellent substrate scope including various xanthenes, thioxanthenes and 9, 10-dihydroacridines and afforded the corresponding ketones with good to excellent yields under catalyst- and additive-free conditions at room temperature.

One-pot synthesis technology of photo initiator 2,4-diethylthioxanthone


Paragraph 0008; 0027-0030, (2020/03/09)

The invention discloses a one-pot synthesis technology of a photo initiator 2,4-diethylthioxanthone. The invention belongs to the field of fine chemical engineering, and specifically relates to a one-pot synthesis technology of a photo initiator 2,4-diethylthioxanthone. According to the technology, thiosalicylic acid (or dithiosalicylic acid) and 1,3-diethylbenzene are taken as the raw materials,concentrated sulfuric acid is taken as a catalyst and a solvent, and under the action of a co-catalyst, condensation reactions are carried out for 4 to 8 hours at a temperature of 0-70 DEG C. Post treatment technologies (condensation, extraction, concentration, and recrystallization) are carried out in one reaction unit; the obtained product is filtered and dried to obtain high purity 2,4-diethylthioxanthone. The technology has the advantages of good selectivity, low reaction temperature, short reaction time, high yield, simple and convenient operation, and high efficiency of single kettle, the equipment investment, the energy consumption, the operation strength, and the production cost are reduced, and the technology is suitable for industrial production.

A sulfur mixed anthracene compound photocatalytic oxidation synthesis method (by machine translation)


Paragraph 0042-0043, (2019/02/04)

The present invention discloses a sulfur mixed anthracene compound photocatalytic oxidation synthesis method, sulfur mixed anthracene compound as a reaction substrate, in order to 2, 3 - dichloro - 5, 6 - dinitrile - 1, 4 - benzoquinone (DDQ) and tert-butyl nitrite (TBN) as catalyst, in order to acetic acid as the reaction additive, to oxygen as the oxidizing agent, the reaction substrate in 1, 2 - dichloroethane in the solvent, and the blue light illumination at normal temperature and under the conditions of reaction, after the reaction is completed after the separation and processed to obtain the sulfur mixed anthracene compound. The synthesizing method of the invention, in order to light the reaction to replace the traditional heating reaction, the energy can be saved; without the use of a transition metal catalyst; under the condition of optimizing, the yield is high.
