-
Paragraph 0030-0083, (2021/09/21)
The invention relates to the technical field of lubricant synthesis, in particular to a lubricant ethylene bis-stearamide (EBS) and a preparation method thereof. The lubricant ethylene bis-stearamide (EBS) is prepared from the following raw materials in parts by weight: 100 parts of stearic acid. 0.5 -1.0 Parts of a compound catalyst, 0.20 -0.45 parts of an antioxidant and 11.7 -12.8 parts of ethylenediamine. The antioxidant is 2, 6 - di-tert-butyl p-cresol. 2 - (2 - Hydroxy -3, 5 -pentylphenyl) benzotriazole, polybutanedioic acid (4 - hydroxy -2, 2, 6, 6 - tetramethyl -1 - piperidinol), β - (4 - 4,4 hydroxylphenyl ', 2 di-tert-butyl) propanoic acid n-octadecanol ester, tris 2,4 - (6 - 3-5 - tert-butylphenyl) propionate, or a combination thereof. Compared with a commercial finished product, the ethylene bisstearamide prepared by the method is more white, good in color and high in finished product quality.

-
Paragraph 0015-0019, (2020/01/25)
The invention relates to a method for catalytic synthesis of ethylene bis-stearamide by composite doped heteropolyacid salt. The method is characterized in that the composite doped heteropolyacid saltis used as a catalyst to catalyze stearic acid and ethylenediamine to synthesize ethylene bis-stearamide, and the structural formula of the composite doped heteropolyacid salt is shown in the specification, wherein in the formula, R is -C16H33, x is 0.4-0.6, and y is 0.4-0.6. The composite doped heteropolyacid salt catalyst has the advantages that the molecular structure of the composite doped heteropolyacid salt catalyst contains lipophilic groups, the catalyst has the characteristics of good affinity to the raw material stearic acid, high specific surface area, suitable acid strength, highsurface acid amount, excellent catalytic performance on the ethylene bis-stearamide synthesis reaction, high product yield, light color and luster, and high purity.

Paragraph 0024; 0025, (2017/04/04)
The invention belongs to the technical field of chemical engineering and particularly relates to a preparation method of vinyl distearamide. The preparation method uses stearic acid and ethylenediamine as reacting raw materials, uses a composite antioxidant prepared by compounding an antioxidant 1076, an antioxidant DLTDP and an antioxidant T501 as a reacting antioxidant and uses a composite catalyst prepared by compounding a p-Toluene sulfonic acid/SAPO-34 supported solid acid catalyst and a phosphoric acid/SiO2-Al2O3 supported solid acid catalyst as a reaction catalyst. The preparation method of the vinyl distearamide is simple in process, no 'three wastes' emission is produced in the process of preparing the vinyl distearamide, the yield is high, and the prepared vinyl distearamide is high in purity, low in chromaticity and narrow in melting range.
