9. The method for preparing diphenyl isodecyl phosphite of any one of claims 1 to 8, which is energy-saving, comprises the following steps:
step 1: opening the sealing cover (3) and adding phosphorus trichloride, decanol and phenol serving as raw materials into the inner side of the preparation shell (11);
step 2: the electric heater (5) is started to drive the electric heating plate (9) to heat the preparation shell (11);
and step 3: a large amount of steam generated under high-temperature reaction generates driving force on a floating air bag (23) to drive an adjusting plate (22) to rotate, so that extrusion force is generated on a limiting spring (21), driving force is generated on a fixing plate (18) through the limiting spring (21), a rotating rod (10) is driven to rotate, and a transverse stirring rod (15) and a vertical stirring blade (17) are driven to rotate inside a preparation shell (11) through the rotating rod (10) to stir;
and 4, step 4: high-temperature steam enters the inner side of the steam accumulation cavity (2) through a transverse air suction pipe (7), is subjected to primary cooling and is pumped out through a liquid discharge pump (4) to prepare diphenyl isodecyl phosphite;
and 5: waste generated by the reaction is discharged into the inner side of the liquid discharging liquid storage bin (12) through the liquid discharging valve (13) by opening the liquid discharging valve (13) so as to be collected and avoid pollution.
