Description
Technical field
The present invention relates to a kind of method for preparing Synolac, especially relate to a kind of method that edible oil prepares Synolac of discarding of utilizing.
Background technology
The method of making Synolac mainly contains two kinds, that is: acid system and oil process.Acid system mainly is that lipid acid, glycerine, tetramethylolmethane, phthalate anhydride are added in the reaction kettle in the lump, is warming up to specified temperature, carries out esterification; Oil process then needs to make with extra care polyvalent alcohols such as soya-bean oil, glycerine, tetramethylolmethane and is warming up to 250 ℃ in the adding reaction kettle earlier, and under the condition that basic catalyst exists, carries out alcoholysis, can add phthalate anhydride after alcoholysis is qualified and carry out next step esterification.Make in the process of Synolac at oil process, very strict to the requirement of refining soya-bean oil, its index is following:
| Project | Index | Unit |
| Color and luster | ≤3 | Fe-Co |
| Acid number | ≤1 | mgKOH∕g |
| Iodine number | 130-140 | gI∕100g |
Only reach the soya-bean oil of this standard, just can directly be used to make Synolac.
All kinds of poor quality oils that discarded edible oil general reference exists in life are like the edible oil that reclaims, the frying oil that uses repeatedly etc.Discarded edible oil the largest source is the oil trap of Large City restaurant water drain.Discarded edible oil also has the low-grade animal oil of quite a few mainly with the soya-bean oil that becomes sour with used soya-bean oil repeatedly to form.But discarded edible cast of oil is very dark, is generally 8-12#, and acid number is up to 30-50 mgKOH ∕ g, and because of containing some animal oil like sheep, pig, ox etc., its iodine number is also on the low side, can't directly be used to make Synolac.
Summary of the invention
The technical problem that the present invention will solve provides a kind of method that edible oil prepares Synolac of discarding of utilizing.
For solving the problems of the technologies described above, a kind of method of utilizing discarded edible oil to prepare Synolac of the present invention may further comprise the steps:
(1), said discarded edible oil is removed the step of water;
(2), remove the step of mechanical impurity with removing discarded edible oil behind the water in the step (1);
(3), remove the step of the discarded edible cast of oil degree behind the mechanical impurity in the set-up procedure (2), make its color and luster degree≤3Fe-Co;
(4), the step of the iodine number of the discarded edible oil of color and luster degree≤3Fe-Co in the set-up procedure (3), make its iodine number reach 130-140 gI ∕ 100g;
(5), to get iodine number in the step (4) be that discarded edible oil 270 Kg of 130-140 gI ∕ 100g add in the reaction kettle, and then the tetramethylolmethane of 130Kg added in the reaction kettle, feeds nitrogen, opens stirring; Heat up, when still temperature rise to 120 ℃, stop stirring; Add an acidic catalyst, open stirring then, continue to be warming up to 250 ℃; The insulation alcoholysis, to sampling and measuring 95% ethanol tolerance be 5 as hot clear end-point, add the 170Kg phthalate anhydride after being cooled to 220 ℃ then; Be warming up to 200 ℃ then, be incubated and begin to survey acid number, viscosity (viscosimetric analysis: sample: 200# paint solvent=11:9, measure) after 3 hours with the form pipe; Every surveyed once at a distance from 0.5 hour, below viscosity reaches 15 S and acid number reach 12 mgKOH ∕ g when following, stop to heat; The suction thinning tank cools off, and adds the 450Kg200# paint solvent, carries out press filtration, barrel filling when being cooled to below 80 ℃ again.
Through adopting above method can utilize discarded edible oil to prepare Synolac, saved refining soya-bean oil.
Embodiment
The present invention is a kind of to utilize discarded edible oil to prepare the method for Synolac, may further comprise the steps:
