50594-66-6 Usage
Chemical Properties
A diphenyl ether, is a combustible, off-white, light tan or brown solid.
Definition
ChEBI: A member of the class of benzoic acids that is 2-nitrobenzoic acid in which the hydrogen at position 5 is replaced by a 2-chloro-4-(trifluoromethyl)phenoxy group. It is a herbicide used for the post-emergence control of a variety of annual broadleaf weeds.
Agricultural Uses
Acifluorfen is a Herbicide: used to control pre-emergent and post-emergent broadleaf weeds and grasses in soybean, peanut, pea and rice crops. It is also registered for use by homeowners as a spot treatment on driveways, sidewalks, and patios. It should not be mixed with oils, surfactants, liquid fertilizers, and other pesticides. Not approved for use in EU countries.

Check Digit Verification of cas no
The CAS Registry Mumber 50594-66-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,0,5,9 and 4 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 50594-66:
(7*5)+(6*0)+(5*5)+(4*9)+(3*4)+(2*6)+(1*6)=126
126 % 10 = 6
So 50594-66-6 is a valid CAS Registry Number.

Paragraph 0021-0036, (2021/02/13)
The invention relates to a method for nitration synthesis of acifluorfen in a microreactor. The method for nitration synthesis of acifluorfen in the microreactor comprises the following steps: proportionally pumping a nitrating agent composed of a solution containing raw materials 3 (2chlorine 4trifluoromethyl phenoxy) benzoic acid, fuming sulfuric acid and fuming nitric acid into the micro-channel reactor in parallel through a metering pump; and reacting to synthesize the 5 (2chlorine 4trifluoromethyl phenoxy) 2nitrobenzoic acid (acifluorfen). The acifluorfen is synthesized by nitration of the micro-channel reactor, the phase contact area is increased, and the mass transfer rate and the reaction rate are high; The heat transfer efficiency is increased, reaction heat is transferred quickly, and safety is improved; The continuous operation is achieved, product quality is stable, operation is flexible, and amplification is easy; under optimized conditions, the reaction conversion rate can reach 99.19%, and the reaction selectivity is 81.08%.
Preparation method of fomesafenbulk drug intermediate acifluorfen
-
Paragraph 0028-0047, (2020/09/12)
The invention provides a preparation method of fomesafenbulk drug intermediate acifluorfen, and belongs to the technical field of pesticides. According to the method, a low-temperature nitrification mode is adopted,nitrylions can be slowly released, so that the reaction tends to be gentle, the selective competitiveness of a target product is enhanced, polynitrification and ectopic nitrification byproducts are inhibited, and the content of the intermediate acifluorfen is effectively increased. The method provided by the invention can be effectively applied to production and application of the fomesafen technical.
