Specific embodiments of today innovation are offered listed below. A type of hydrogenated oil of today innovation, takes on vegetable oils and also butter such as palm oil, soybean oil, cottonseed oil, peanut oil, rapeseed oil, sesame oil, olive oil, corn oil, rice bran oil, coconut oil, chocolate oil and sunflower oil, 2 or even more kinds of pet fats such as mutton oil, lard oil and also fish oil are made use of as resources, and also copper-nickel binary stimulant is contributed to make it via hydrogenation reaction.
Palm oil is made from fresh hand fruit, to start with a series of processes such as sanitation, threshing, soaking, pushing, filtering, stalling, centrifugal separation, vacuum dehydration, etc to acquire hand crude oil, and after that with degumming, deacidification, decolorization, filtering, deodorization as well as various other chemical refining procedures to acquire refined hand oil. Palm oil is mostly made up of triglycerides, which additionally includes a big amount of glycerol compounds and a percentage of non-triglycerides as well as diglycerides. Saturated fatty acids as well as unsaturated fatty acids each represent concerning 50% in hand oil. This equivalent split establishes that hand oil has much better oxidation security than various other veggie oils. The typical density of palm oil is about 0.889 g/ml (50 ° C), the average iodine worth (Webster) has to do with 52.9, the average melting point has to do with 34.2 ° C, as well as the average refractive index (50 ° C )has to do with 1.455.
Soybean oil is made from soybeans. It is gotten with a collection of procedures such as pretreatment, pressing (or solvent) leaching, as well as solvent recovery from oil, and afterwards degumming and/or alkali refining, decolorization, as well as deodorization. have to. Unrefined soybean oil is generally made up of triglycerides, which also contains a specific quantity of phospholipids, unsaponifiable substances, free fatty acids, etc. The loved one density of soybean oil is about 0.9175 (25 ° C), the ordinary iodine worth (Webster) is about 131.6, the freezing point of fatty acid is 24′ C, and also the average refractive index (25 ° C )has to do with 1.473.
Cottonseed oil is made from cottonseed, which is to start with acquired by delinting, shelling, as well as dividing cotton kernels, after that rolling as well as drawing out to get unrefined cottonseed oil, and afterwards refining, decolorizing, and also ventilating. Cottonseed oil is made up of gossypol, phospholipids, sterols, resins, hydrocarbons and associated pigments. The typical iodine value (Webster) of cottonseed oil is about 110, the isothiocyanate worth has to do with 65, the typical saponification worth has to do with 195, the relative density (25 ° C )is about 0.917, the ordinary melting point has to do with 12 ° C, and the typical refraction The proportion (20 ° C )has to do with 1.472.
A lot of the butter comes from beef livestock. The top quality of the steamed butter is usually good and does not need to be improved; if the totally free fatty acid of the butter is higher than 0.3%, or has colloids and also protein objects, it should be improved with antacids. Guaranteed specific oxidation security. Normal net tallow relative thickness (99 DEG C) is 0.860, as well as refractive index (40 DEG C, Zeiss) is 48, as well as iodine value is 42, and also fatty acid freezing point is 43 DEG C.
A sort of preparation method of hydrogenated oil as well as fat of the here and now invention, i.e. animal as well as veggie wax, its handling action is:
1. Mix the raw materials, take 2 or more vegetable oils and also animal fats as basic materials, make the sum of the percentages reach 100%, then put them right into the autoclave, close the lid tightly, and stir at 650 ~ 1500rpm Totally mixed in the state;
2. Add the catalyst, and also after the raw products are totally mixed, add the copper-nickel binary catalyst and afterwards fully stir and also mix;
3. Evacuation of the hydrogenation system, after the raw products and also the catalyst are totally stirred as well as blended, the activator is evacuated to a vacuum of 9.48 × 104 Pa, and after that 0.3 ~ 0.5 Mpa of nitrogen is charged right into the reactor, and also the air vent port After decompression to 0.15 MPa, proceed vacuuming to 9.48 × 104 Pa vacuum level, maintain the vacuum state of activator after leaving;
4, the heating of the hydrogenation system, open the stirring device of the system, make the stirring speed reach 650 ~ 1500rpm, the temperature level of the activator is elevated to 170 ~ 240 ° C by the temperature controller;
5. For the hydrogenation of the hydrogenation system, under the state of response temperature level 170 ~ 240 ° C and also stirring rate 650 ~ 1500rpm, fill hydrogen into the reactor to make the pressure reach 0.3 ~ 2Mpa, and also preserve this stress to react for 45 ~ 120 mins (min), hydrogenated oil can be prepared.
Usage hand oil and soybean oil as resources, as well as blend them according to the proportion of 1:1, to make sure that the amount of the proportions reaches 100%;.
Its technical problem to prepare technique is:.
Mixing speed is 650 ～ 1000rpm, as well as the usage of copper-nickel binary catalyst is 0.03 ～ 0.5% of basic material overall quantity, as well as reaction temperature level is 180 ～ 240 ℃, and stress is 0.3 ～ 2Mpa, and also reaction time: 60 ～ 90 minutes (miro. The performance index of the product is: freezing point, c, penetration/0. 1mm, kinematic viscosity/mm2/s39.3 43 9, 888.
