General Description
1,2-Propadienylphosphonic Acid, also known as Propargylphosphonic Acid, is a chemical compound with the formula C3H3O3P. It belongs to the class of organic compounds known as organophosphonic acids and derivatives. These are organic compounds containing phosphonic acid or a derivative, which is a compound containing a phosphorus atom bonded to three oxygen atoms (one of them through a double bond) and one carbon atom. It is sometimes used in chemical synthesis due to its reactivity in various organocatalytic reactions, including Michael additions, aldol reactions, and Diels-Alder reactions. Despite this, information on its safety, toxicity, usage, and environmental effects is relatively limited.
Check Digit Verification of cas no
The CAS Registry Mumber 34163-96-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,4,1,6 and 3 respectively; the second part has 2 digits, 9 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 34163-96:
(7*3)+(6*4)+(5*1)+(4*6)+(3*3)+(2*9)+(1*6)=107
107 % 10 = 7
So 34163-96-7 is a valid CAS Registry Number.

Synthesis method of intermediate allene phosphonic acid
-
Paragraph 0009, (2018/10/19)
The invention discloses a synthesis method of intermediate allene phosphonic acid. The synthesis method includes: taking phosphorus trichloride, propargyl alcohol, chloroform, dioxane, Ni (NO3) 2 6H2O, Fe (NO3) 3 9H20 and sodium citrate as main raw materials; performing substitution reaction on propargyl alcohol and phosphorus trichloride under the action of a catalyst to generate propylene dioxychloride and then rearrangement in chloroform to form the intermediate allene phosphonic acid. The synthesis process is less in side reaction, short in synthesis step, simple in aftertreatment and moderate in reaction condition, and yield is greatly increased as compared with that of a traditional process.
