| titleOfInvention | Manufacturing method of phosphate ester |
| abstract | (57) [Summary]nA method for producing a low-viscosity liquid metal-rich triallyl phosphate ester having a low content of triphenylphosphoric acid, comprising: (a) converting a phenol containing 2 to 12 carbon atoms in the presence of a strong acid catalyst; An alkylation reaction step which produces a reaction product comprising a mixture of meta or para alkyl phenols by reacting with an olefin; and (b) heating the mixture of alkyl phenols of the alkylation reaction step in the presence of a strong acid catalyst. A transalkylation step to increase the content of meta isomers in the mixture to at least 20% while keeping the amount of phenol below 22%; and (c) phosphorylating the mixture of alkylphenols in the transalkylation step. A phosphorylation step of reacting with an oxidizing agent, wherein said step (a) and (b) Toriarirurin esters method for generating a strong acid catalyst, acid strength is lower Bronsted acids than zeros. A more preferred catalyst is an activated viscosity such as bentonite, montmorillonite or acid clay. The alkylation and transalkylation reaction steps are carried out at a temperature between 100 ° C and 200 ° C, preferably between 150 ° C and 180 ° C. |
