| titleOfInvention | Triphenyltin chloride preparation method |
| abstract | The invention relates to a triphenyltin chloride preparation method. The method comprises the following steps: melting metallic tin, splashing the metallic tin with cold water to form tin flowers, adding the tin flowers to a reaction kettle, adding liquid chlorine, and dissolving and stirring to generate tin tetrachloride; mixing sodium with xylene to disperse sodium, putting the obtained sodium and xylene mixture in a second reaction kettle, adding chlorobenzene, and heating the second reaction kettle to 35-50DEG C in order to obtain phenyl sodium; mixing chlorobenzene with tin tetrachloride and phenyl sodium to obtain tetraphenyltin; adding hydrochloric acid to tetraphenyltin to carry out acid precipitation, and carrying out pumping filtration of a mixed solution obtained after the acid precipitation to obtain tetraphenyltin; and disproportionating tetraphenyltin and aluminum trichloride to obtain triphenyltin chloride. The method has the advantages of simple operation and high conversion rate. |
