1. 染料及中間體

1. Dyes and intermediates

精萘是合成蒽醌系染料的核心原料,可制成:

Naphthalene is the core raw material for synthesizing anthraquinone dyes, which can be made into:

H酸(染料中間體):占全球萘消耗量的35%以上,用于生產(chǎn)酸性、活性染料;

H-acid (dye intermediate): accounting for over 35% of global naphthalene consumption, used for the production of acidic and reactive dyes;

2-萘酚:通過磺化、堿熔工藝制得,是合成偶氮染料(如直接大紅4B)的關(guān)鍵中間體;

2-Naphthol: produced through sulfonation and alkali melting processes, it is a key intermediate for the synthesis of azo dyes (such as Direct Red 4B);

克列夫酸:用于制造媒染染料,提升紡織品色牢度。

Klevic acid: used in the manufacture of mordant dyes to enhance the color fastness of textiles.

2. 合成材料

2. Synthetic materials

萘系減水劑(如FDN系列):通過磺化、縮合反應(yīng)制成,可提升混凝土抗壓強度15%-25%,占中國萘消費量的40%;

Naphthalene based water reducing agents (such as FDN series): made through sulfonation and condensation reactions, can improve the compressive strength of concrete by 15% -25%, accounting for 40% of China's naphthalene consumption;

萘系樹脂:

Naphthalene resin:

萘酚甲醛樹脂:耐熱性達(dá)200℃以上,用于電子封裝材料;

Naphthol formaldehyde resin: with a heat resistance of over 200 ℃, used as an electronic packaging material;

萘系環(huán)氧樹脂:介電常數(shù)≤3.5,是5G基站PCB板的理想基材。

Naphthalene based epoxy resin: with a dielectric constant of ≤ 3.5, it is an ideal substrate for 5G base station PCB boards.

3. 醫(yī)藥及農(nóng)藥

3. Pharmaceuticals and pesticides

維生素K3(甲萘醌):全球年產(chǎn)量超2萬噸,飼料添加劑領(lǐng)域需求旺盛;

Vitamin K3 (menaquinone): With a global annual production of over 20000 tons, there is a strong demand in the field of feed additives;

52054a3c-9b13-4896-b8a3-473c914ff4e9

萘普生(非甾體抗炎藥):通過Friedel-Crafts酰基化合成,解熱鎮(zhèn)痛效果顯著;

Naproxen (nonsteroidal anti-inflammatory drug): synthesized through Friedel Crafts acylation, it has significant antipyretic and analgesic effects;

西維因(氨基甲酸酯類殺蟲劑):以萘為起始原料,對棉鈴蟲防效達(dá)90%以上。

Sevine (carbamate insecticide): Starting from naphthalene, it has a control effect of over 90% against cotton bollworms.

4. 功能化學(xué)品

4. Functional chemicals

樟腦(合成路線):經(jīng)異構(gòu)化、氧化制得,用于醫(yī)藥和香料工業(yè);

Camphor (synthetic route): obtained by isomerization and oxidation, used in the pharmaceutical and spice industries;

十氫萘(高能燃料添加劑):加氫產(chǎn)物,可提升航空煤油熱值10%-15%;

Decahydronaphthalene (high-energy fuel additive): a hydrogenation product that can increase the calorific value of aviation kerosene by 10% -15%;

萘系表面活性劑:如烷基萘磺酸鹽,在三次采油中作為驅(qū)油劑使用。

Naphthalene based surfactants, such as alkyl naphthalene sulfonate, are used as oil displacement agents in tertiary oil recovery.

5. 新材料領(lǐng)域

5. New materials field

石墨烯前驅(qū)體:通過氣相沉積法(CVD)可制備高質(zhì)量石墨烯薄膜;

Graphene precursor: High quality graphene films can be prepared by vapor deposition (CVD) method;

有機半導(dǎo)體材料:如并五苯類似物,載流子遷移率可達(dá)5 cm2/V·s;

Organic semiconductor materials, such as pentacene analogues, have a carrier mobility of up to 5 cm 2/V · s;

鋰電負(fù)極材料:熱解產(chǎn)物硬碳比容量>300 mAh/g。

Lithium battery negative electrode material: The hard carbon specific capacity of the pyrolysis product is greater than 300 mAh/g.
