Problems solved by technology

[0003] At present, titanate is mostly used as a catalyst in industry, and it reacts in a homogeneous phase. Titanate catalysts are not easy to recycle and reuse.
Moreover, titanate decomposes quickly when it meets water, and a large amount of water is generated in the esterification reaction. During the reaction process, if the water generated by the reaction cannot be removed in time, the catalytic efficiency will be affected, resulting in a slow reaction rate, and even catalyst loss. living phenomenon
After the reaction is finished, post-treatments such as neutralization and water washing are required, and waste liquid and waste water are generated during the post-treatment process, causing certain pollution

Embodiment 1

[0021] Catalyst preparation: 7.6g cesium nitrate (CsNO 3 ), 9.8g lanthanum nitrate hexahydrate [La(NO 3 ) 3 ·6H 2 O] and 12g neodymium nitrate hexahydrate [Nd(NO 3 ) 3 ·6H 2 O], mixed into 40g of water, stirred for 4h, dried, then calcined in a muffle furnace at 650°C for 5h, and then heated to 850°C for 8h to obtain powder A. 14.8g copper nitrate trihydrate (CuNO 3 ·3H 2 O) and 14.6 g of phosphoric acid (H 3 PO 4 ) was dissolved in 120g deionized water to obtain solution B. 190g ammonium molybdate tetrahydrate [(NH 4 ) 6 Mo 7 o 24 4H 2 O] was dissolved in 430g deionized water, then 11.7g ammonium vanadate (NH 4 VO 3 ) was suspended therein to obtain suspension C. Add powder A to suspension C under stirring, then drop solution B into it, then stir in a sealed container at 120°C for 30h to obtain a slurry. Dry the slurry to obtain a catalyst precursor, and finally bake it in a muffle furnace at 450° C. for 15 hours. After cooling, it is broken into 80-100 mesh...

Embodiment 2

[0027] Catalyst preparation, catalyst pretreatment method, catalyst dosage, raw material dosage, and water-carrying agent dosage are the same as in Example 1, except that the synthesis reaction temperature is adjusted to 210° C., and the reaction results are shown in Table 1.

Embodiment 3

[0029] Catalyst preparation, catalyst pretreatment method, reaction temperature, raw material consumption, entrainment agent consumption are the same as embodiment 1, just catalyst consumption is adjusted to 2% of reaction substrate weight, i.e. 15.4g, and reaction result is shown in Table 1.

Abstract

The invention belongs to the technical field of fine chemicals preparation and discloses a method for synthesizing diisostearyl malate. The method includes: using malic acid and diisostearyl to synthesize diisostearyl malate under action of a solid catalyst which is a compound oxide composed of non-metallic element P, alkali metal element Cs, transition metal elements V, Cu and Mo and rare earth metal elements La and Nd, wherein reaction temperature is 180-240 DEG C. The solid catalyst is reusable, and the method has the advantages of environment friendliness, safety and high malic acid esterification rate.

Description

technical field [0001] The invention belongs to the technical field of preparation of fine chemical products. Specifically, a solid composite oxide is used as a catalyst to catalyze malic acid and diisostearyl alcohol to synthesize diisostearyl malate. Background technique [0002] Diisostearyl malate is an important raw material for cosmetics. It is a highly polar oil with excellent dispersibility for powders and pigments, and also has good emollient effect. It can form a thick layer Its film-like structure has a rich silky touch, which is very suitable for lip cosmetics and can increase the brightness of lipsticks and lip glosses. Chinese patent CN103893067A discloses a camellia oil formula for protecting lips in winter with diisostearyl malate as an important raw material, and diisostearyl malate mainly plays the role of lubricating lips. And Chinese patent CN104414879A discloses a kind of lip gloss formula of protecting double lips with diisostearyl malate as important ...
