Source carnauba wax is a natural plant wax extracted from the leaves of palm trees that grow in northeastern Brazil, South America. It plays an important role in preventing the evaporation of water in dry areas. In these areas where industries are poor, carnauba wax plays a very important role in revitalizing the regional economy. The export of carnauba wax is attracting increasing attention as a bridge between agriculture and industry. Characteristics (1) Glossy is a major function of carnauba wax. It has been widely used in coating films in the fields of sugar-coated chocolate, granular chewing gum, nutritional food tablets, food and medicine, and has also been widely used in automobile wax, floor wax, leather polish, etc. (2) Brazil |

Specific details are as follows: 1, used for food ingredients: polishing agent and polishing agent of chewing gum, soft and hard bean gum candy and chocolate; 2, used for building materials: Floor Wax: resulting in an unexpected polishing and lightening effect. Rubber Products: can enhance the hardness of rubber, prevent the sun crack generated by the rubber hardening. Especially for the building fabric is very useful. Asphalt and floor joint materials: to improve its water resistance and adhesion; Roof materials: to improve water resistance and durability. 3, daily areas: Shoe Polish: suitable for oil or bottom shoe polish polishing furniture: is still the bottom or bottom of the incomparable polishing agent. Leather Products: used for leather coating and preservation, so that the leather clothing and leather bag has a bright luster and can also be used as leather polishing and leather Oil Primer. Carbon paper and printing ink: known as the "blood of life" of the carbon paper industry ". 4. Industrial field: used for the exposed part of the package in the aircraft, to provide long-lasting protection and reduce surface friction, in order to improve its flight speed. Chemical Industry: use in a wide range of forms and formulations. Synthetic wax: enters the composition to make it an all-weather bright coating for cars, trucks, buses, and trains. Foundry: used in the process of wax and zinc plating for casting. 5. Agricultural field: the effect of Brazil Brown resting wax on the growth and development of brown rot and soft rot fungi in vitro and the effect of two pathogens on nectarine and plum fruit surface can inhibit brown rot and soft rot to some extent. 6, other uses: in soap, lipstick, ointment, candles, matches, paint (paint), varnish, plaster, artificial fruit, phonograph record production has a wide range of uses. |
| synthesis process | Brazilian palm is obtained by manual extraction through a complex process, and there is no disclosed preparation process at present. |
| determination of content | experiments by Zhicong de et al showed that the standard sample solution was directly derivatized with trimethylsilane (BSTFA), after the sample was extracted by ultrasonic heating, it was derivatized with BSTFA, and directly detected by hydrogen flame ionization detector (FID) to obtain good detection results. The specific detection parameters are set as follows: column RTX65-TG:30 m x 0.32mm (I. d.),0.25 m. Column temperature: based on 200 ℃, rise to 370 0C at 20 0C /min, keep for 20 min, run time 37 min; Inlet temperature 320 ℃; Detector temperature 370 ℃; the flow rate of hydrogen was 40 mu Min, the flow rate of air was 400 mu Min, and the injection volume was 1 μL. In order to achieve better separation effect on high boiling point substances, the program pressure-up mode is adopted at the same time: the column flow rate is 1.0 mL/min, and the column flow rate is maintained for 17 min, the column flow rate was increased to 100 mL/min at 2.0 mL/min 2 for 4 min, and the column flow rate was further increased to 100 mL/min at 3.0 mL/min 2. |
