The physicochemical property of sweet three ester in 4 embodiment of table and comparative example.
Note: the ratio of SFC when SFC and 35 DEG C when the ratio of SFC10:SFC35 refers to 10 DEG C.
As can be seen from the above table, the plant candle is substantially greater than 45% with 35 DEG C of grease of SFC, generally higher than
48%, preferably greater than 50%.When in fat ranges of the invention, the performance of the grease reaches optimal balance, neither
It cracks also oil-tight, is provided simultaneously with good demolding performace and chalking resistance energy.
The candle appearance that embodiment 1-4 is obtained it can be seen from above-mentioned data is good, no hickie and cracking phenomena, together
When it is oil-tight, be easy demoulding, be a kind of extraordinary column wax, and each candle obtained in comparative example has various differences
Defect.Comparative example 1-3 is also using the transesterification product of hydrogenation rice bran rouge, but they have cracking phenomena, and fusing point
When lower, permeability and hickie phenomenon are also had.This is because the SFC10:SFC35 of these transesterification products not 1.4-1.8 it
Between, so that its fusing point is different from embodiment 1-3.Comparative example 4-5 (hydrogenated soybean oil transesterification products and palm stearin ester
Trade-to product) have fusing point similar to Example 1, but also in that its SFC10:SFC35 differed with the range of 1.4-1.8 compared with
Greatly, the problem of candle performance obtained is also very poor, exists simultaneously more difficult demoulding, permeability, hickie and cracking.These results illustrate oil
Rouge must control SFC10:SFC35 in a certain range, and the candle of preparation does not just have above-mentioned defect.
Comparative example 6 is the candle of the hydrogenated oil and fat preparation before 1 transesterification of embodiment, iodine value, fusing point and FAC and implementation
The phenomenon that example is same or similar, but there are still crackings, the SFC of this and the two, especially SFC10:SFC35 difference causes.It is right
Than embodiment 7 and the SFC10:SFC35 value having the same of embodiment 2, similar iodine value, FAC, but the candle that they make is still
The problems such as there are frosting and permeabilitys.This may be to illustrate to hydrogenate rice bran rouge because not using rice bran rouge in the comparative example
Play a significant role in terms of assigning candle excellent properties.Although comparative example 8 also uses hydrogenation rice bran rouge, and it is each
Item index is also similar to Example 2, and still, the performance of candle is also bad, this may be because it uses different transesterifications
The mixture of product does not do last transesterification process, and in embodiment 3, using the grease of transesterification after first mixing,
Candle performance is with regard to fine, and the result shows carrying out overall transesterification to grease is to promote plant base candle to have improvement result.
From the foregoing, it will be observed that only using the ester interchanged prod of containing hydrogenated rice bran rouge, and its SFC10:SFC35 ratio should be
Between 1.4-1.8, preferable performance is just had by its candle made, and is limited by grease iodine value, FAC, fusing point etc. smaller.
The foregoing is merely illustrative of the preferred embodiments of the present invention, the substantial technological content model being not intended to limit the invention
It encloses, substantial technological content of the invention is broadly defined in the scope of the claims of application, any technology that other people complete
