There are no customs supervision conditions for the export of mesitylene by sea, but it is listed in the 2015 hazardous chemicals catalog, so sea export requires commercial inspection.
The molecular structure of mesitylene (also known as 1,3,5-trimethylene, formula C9H12) is benzene ring C atom formed by sp2 hybrid orbital σ Bond, other C atoms formed in sp3 hybrid orbitals σ A bond is a functional group that exists in various organic compounds. It is widely found in coal tar and some petroleum. Mesitylene is a colorless transparent liquid that is insoluble in water, soluble in ethanol, and can be dissolved in any proportion in benzene, ether, and acetone. It is toxic, flammable, and explosive. Freezing point -44.72 ℃, melting point -44.7 ℃, boiling point 164.7 ℃, relative density 0.8652 (20/4 ℃). Mesitylene is an important organic synthesis raw material, an intermediate for various dyes, and can also be used in the production of antioxidants, polyester resin curing agents, stabilizers, alkyd resin plasticizers, and so on. Due to the fact that mesitylene is a good solvent, it is flammable, irritating, and has a low freezing point. In the electronics industry, it is used as a developer for silicone photosensitive films.
Production method: 1. It is obtained by separating C9 aromatic hydrocarbons. 2. In reforming heavy aromatic hydrocarbons, about 11.8% of trimethylbenzene is present. 3. The isomerization method using trimethylbenzene as raw material yields a single pass yield of 21.6% and a purity of over 95% for 1,3,5-trimethylbenzene obtained by fractionation. 4. Acetone can be dehydrated and synthesized with a yield of 13% -15% under the catalysis of sulfuric acid.
Mesitylene is a Class 3 flammable liquid hazardous material, with a toxicity classification of low toxicity. Dangerous goods export by sea requires a hazardous packaging certificate, and some products cannot be replaced with a limited quantity certificate. For Class 3 dangerous goods export by sea, both LCL and FCL can be used, and direct loading by the ship is also required. Special attention should be paid to the flash point when exporting Class 3 dangerous goods by sea. If the flash point is too low, the shipping company may not accept it. Flammability hazard characteristics: When exposed to open flames, high temperatures, or oxidizing agents, it is more flammable and produces irritating smoke during combustion. During storage and transportation, the warehouse is ventilated and dry at low temperature, and stored separately from the oxidant.
Declaration elements: 1: Product name; 2: Brand type; 3: Export benefits; 4: Component content; 5:GTIN； 6:CAS； 7: Others.
The information required for the export of mesitylene by sea includes:
Booking information: Freight authorization letter, English version MSDS, scanned copy of dangerous goods certificate, and shipping company application form.
Declaration materials: Declaration authorization letter, packing list, English version MSDS, original hazardous packaging certificate, hazardous packaging technical manual, etc.
Customs declaration materials: customs declaration form, customs declaration authorization letter, packing list, invoice, declaration elements, and commodity inspection form.
Maritime export process: booking in advance - pre loading into the warehouse - declaration - customs clearance - entering the port - boarding - issuing a bill of lading (usually about two working days after the ship departs)
Book 10 days in advance for ocean routes, and 2-3 weeks in advance for ocean routes.
