Description
【Technical field】
The present invention relates to a kind of waste grease prepares the process of fatty acid glycerine borate ester
【Background technology】
Waste grease is actually a concept for referring to, and is common name of the people for all kinds of poor oils in life.Abandoned oil can be divided into following a few classes：One is the abandoned oil of narrow sense, greasy floating thing that will be in sewer or by hotel, the leftovers of restaurant, leftovers（Common name swill）Through the oil that simply processes, extract；Two is the oil of output after pork inferior, haslet, pigskin processing and refinement；Three are exceeded after regulation requirement for the oily access times of fried food, are again repeated the oil for using or reusing after adding some fresh oils thereto.It is to solve the extraordinary approach of abandoned oil using abandoned oil ester-interchange method manufacture fatty acid polyethylene glycol ester.
The fatty acid glycerine borate ester gone out synthesized by the present invention is dissolved in multiple organic solvents, is in dispersed in water, with emulsification, solubilising, wetting, softness.Emulsifying agent, softening agent is done in textile；Cleaning agent, lubricant, brightener is done in metal-processing industry；In paper-making industry, paper starch coat thickener, stabilizer is done；Grease type emulsification can also be done；Coating, the grinding aid of printing-ink.It is the new material of modern environment protection reproducible utilization, with good Social benefit and economic benefit.
【Content of the invention】
A kind of waste grease of the present invention prepares the process of fatty acid glycerine borate ester：
1. the pretreatment of waste grease：Pre-treatment is carried out using pre- esterification method to waste grease, Plus acidic catalyst, operating pressure 0.3-0.4kg/c in kettle, at 65-85 DEG C, time 1-2 hour, control refine the acid value≤3.5mgKOH/g of crude oil to temperature control.
2. waste grease fatty acid methyl esters and glycerine are refined：After discarded oil refining crude oil pre-esterification, under conditions of having base catalyst, formal esterification is carried out；It is 1 to add base catalyst, abandoned oil and methyl alcohol molar ratio:4-1:9th, temperature control 70-80 DEG C, methanol eddy reaction time 1 hour.Waste grease fatty acid methyl esters and glycerine is obtained, waste grease fatty acid methyl esters and glycerine is separated, then is washed, distills, obtain refining waste grease fatty acid methyl esters and glycerine.
3. abandoned oil methyl esters is refined：Through washing, charcoal absorption, filter filtration, vacuum distillation, methyl esters yield more than 97% is refined.
4. glyceryl borate：Metering amounts of glycerol is put in reactor, stirring, metered boric acid, leads to nitrogen, and pressurization 90-95kPa, temperature control synthesize glyceryl borate in 130-140 DEG C, reaction time 3-4h.
5. the synthesis of fatty acid glycerine borate：Refined abandoned oil methyl esters carries out the synthesis of fatty acid glycerine borate with ester-interchange method；Abandoned oil methyl esters and glyceryl borate reaction mol ratio and weight is calculated, is separately added in reactor, adds under base catalyst, temperature control 80-100 DEG C, vacuum state after reaction 1.5-2 hour, synthesize fatty acid glycerine borate；Being warming up to 70 ± 5 DEG C has methyl alcohol to flow out, and reaches 110 DEG C to temperature, and methyl alcohol effluent stops substantially；Stop vavuum pump, reaction continues 2 hours, carries out that material is aging, and ageing time is finished, and 35 ± 5 DEG C are cooled to rapidly, discharging.
The fatty acid glycerine borate ester gone out synthesized by the present invention, outward appearance are 5-7, acid value in micro- Huang to Off-white solid, pH value（mgKOH/g）≤ 5, saponification number（mgKOH/g）75～95, moisture≤1.0%.
【Specific embodiment】
The present invention is using refined crude oil and the methyl alcohol pre-esterification of abandoned oil.1000 kilograms of abandoned oil of metering, heats up 40 ± 5 DEG C, measures 80 kilograms of methyl alcohol, Plus acidic catalyst 0.5%, operating pressure 0.4kg/c in kettle, temperature control at 75 ± 5 DEG C, 1 hour reaction time.Control refines the acid value≤3.5mgKOH/g of crude oil.
After the present invention discards oil refining crude oil pre-esterification, formal esterification is carried out under conditions of having base catalyst.
Method：300 kilograms of metering methyl alcohol is added in 16 kilograms of input reactors of base catalyst, temperature heats up, 70 ± 5 DEG C, the 1 hour methanol eddy reaction time of control, obtain waste grease fatty acid methyl esters and glycerine, after static 20 minutes, waste grease fatty acid methyl esters and glycerine is separated, then by washing, distillation, obtains refining waste grease fatty acid methyl esters.
Abandoned oil methyl esters of the present invention is refined：Washing, charcoal absorption, filter filtration, vacuum distillation, are processed through this four step, and the high-boiling components in methyl esters, pigment, impurity can be removed well.
1. wash：Temperature control is stirred 20 minutes at 70 ± 5 DEG C,
2. charcoal absorption：Temperature control is stirred 20 minutes at 70 ± 5 DEG C.
3. filter is filtered：Charcoal absorption methyl esters material enters filter, and it is stand-by that the methyl esters after filtration enters another storage tank.
4. vacuum distillation：1/2nd of whole methyl esters material are added, after distillation 1-2 hour, is lowered the temperature 50 ± 5 DEG C, adds second half methyl esters material.When seeing nothing effluent in visor is observed, it was demonstrated that methyl ester distilled finish.Distillation vacuum degree control：700-760mmHg, vapo(u)rizing temperature control：150-250℃.When temperature of reaction kettle is down to 100 ± 5 DEG C, vacuum is closed.Refined methyl esters yield 94-97%.
Abandoned oil aliphatic acid boroglycerol ester exchange synthetic method of the present invention：
Monoesters synthesis is to calculate to feed intake with 1mol waste grease fatty acid methyl esters and 1mol glyceroborate, and base catalyst is calculated with the 0.5% of whole material.
