      涂料
      coating
      順酐在涂料方面的應(yīng)用主要是醇酸樹(shù)脂涂料和氨基樹(shù)脂涂料。醇酸樹(shù)脂涂料是18大類涂料中消費(fèi)量大的一類,產(chǎn)量和消費(fèi)量約占涂料總量的三分之一。醇酸樹(shù)脂具有良好的附著力、光澤度和抗腐蝕等性能,廣泛用于建筑涂裝、機(jī)械和汽車涂裝、家俱以及防腐涂裝;氨基樹(shù)脂涂料也有良好的硬度、光澤和保光保色性能,廣泛用于輕工家電產(chǎn)品的裝飾涂裝。2003年全國(guó)醇酸樹(shù)脂涂料和氨基樹(shù)脂涂料的產(chǎn)量估計(jì)為75萬(wàn)噸,消耗順酐約1.14萬(wàn)噸。預(yù)計(jì)“十一五”期間,醇酸樹(shù)脂涂料和氨基樹(shù)脂涂料仍將是涂料行業(yè)的主力品種,水性涂料、粉末涂料、高固體分涂料等低污染型涂料將以較快的速度發(fā)展,但所占比重不會(huì)有太大的變化。
      The main applications of maleic anhydride in coatings are alkyd resin coatings and amino resin coatings. Alkyd resin coatings are the largest consumer among the 18 major categories of coatings, with the output and consumption accounting for about one-third of the total amount of coatings. Alkyd resin has good adhesion, glossiness and corrosion resistance, and is widely used in architectural coating, machinery and automobile coating, furniture and anti-corrosion coating; Amino resin coatings also have good hardness, gloss, light and color retention properties, and are widely used for decorative coating of light industrial and household appliances. In 2003, the national production of alkyd resin coatings and amino resin coatings was estimated at 750000 tons, and the consumption of maleic anhydride was about 11400 tons. It is expected that alkyd resin coating and amino resin coating will still be the main varieties in the coating industry during the "Eleventh Five-Year Plan" period. Water-based coating, powder coating, high-solid coating and other energy-saving and low-pollution coatings will develop at a faster speed, but the proportion will not change much.
      酒石酸
      tartaric acid
      酒石酸主要用作食品酸味劑,其鹽類用作鏡子鍍銀和金屬處理。在紡織工業(yè)中,酒石酸也可用在制革和電訊器材行業(yè)。
      Tartaric acid is mainly used as food acid, and its salts are used for mirror silver plating and metal treatment. In the textile industry, tartaric acid can also be used in the tanning and telecommunication equipment industries.
      年L-型和dl-型酒石酸產(chǎn)能估計(jì)約1.1萬(wàn)噸,產(chǎn)量約8500噸,消耗順酐約7900噸。由于近年來(lái)美國(guó)和日本的L-型酒石酸商向轉(zhuǎn)移投資,使國(guó)內(nèi)L-型酒石酸產(chǎn)品產(chǎn)能迅速增長(zhǎng)。目前國(guó)內(nèi)L-型酒石酸年產(chǎn)能已達(dá)到1萬(wàn)噸以上,dl-型酒石酸產(chǎn)品的年產(chǎn)能也達(dá)到約2萬(wàn)噸。
      The annual production capacity of L-type and dl-type tartaric acid is estimated to be about 11000 tons, the output is about 8500 tons, and the consumption of maleic anhydride is about 7900 tons. In recent years, the production capacity of domestic L-tartaric acid products has increased rapidly due to the transfer of investment by L-tartaric acid producers in the United States and Japan. At present, the annual capacity of L-type tartaric acid in China has reached more than 10000 tons, and the annual capacity of dl-type tartaric acid products has also reached about 20000 tons.
      潤(rùn)滑油添加劑
      Lubricant additive
      目前潤(rùn)滑油添加劑產(chǎn)品中以無(wú)灰分散劑和金屬清凈劑為主,占潤(rùn)滑油添加劑總消費(fèi)量的70%,其中只有無(wú)灰分散劑的需要消耗順酐。
      At present, ash-free dispersant and metal detergent are the main products of lubricating oil additives, accounting for 70% of the total consumption of lubricating oil additives. Only the production of ash-free dispersant needs to consume maleic anhydride.
      順酐廠家
      農(nóng)藥
      pesticides
      順酐在農(nóng)藥中,主要用于殺蟲(chóng)劑,包括有機(jī)磷殺蟲(chóng)劑如馬拉硫磷和達(dá)凈松,以及除蟲(chóng)菊酯殺蟲(chóng)劑如胺菊酯。
      Maleic anhydride is mainly used in pesticide production, including organophosphorus insecticides such as malathion and dapsone, and pyrethroid insecticides such as permethrin.
      琥珀酸及酐
      Succinic acid and anhydride
      琥珀酸(丁二酸)主要用于涂料、染料、粘合劑和醫(yī)藥方面。由琥珀酸的醇酸樹(shù)脂具有良好的曲撓性、彈性和抗水性;琥珀酸的二苯基酯是油料中間體,與氨基蒽醌反應(yīng)后生成蒽醌染料;琥珀酸在醫(yī)藥工業(yè)中可用來(lái)磺胺藥、維生素A、維生素B和止血藥等;琥珀酸在造紙、紡織行業(yè)中也有廣泛的用途,還可用作潤(rùn)滑劑、照像化學(xué)品和表面活性劑的原料。
      Succinic acid (succinic acid) is mainly used in coatings, dyes, adhesives and pharmaceuticals. Alkyd resin produced from succinic acid has good flexibility, elasticity and water resistance; Diphenyl ester of succinic acid is an oil intermediate, which reacts with aminoanthraquinone to form anthraquinone dye; Succinic acid can be used in the pharmaceutical industry to produce sulfa drugs, vitamin A, vitamin B and hemostatic drugs; Succinic acid is also widely used in papermaking and textile industries, and can also be used as raw material for lubricants, photographic chemicals and surfactants.
      四氫苯酐
      Tetrahydrophthalic anhydride
      四氫苯酐作為有機(jī)合成中間體,可制取農(nóng)藥敵菌丹、克菌丹等,也可制取增塑劑、環(huán)氧樹(shù)脂固化劑、不飽和聚酯樹(shù)脂、無(wú)溶劑漆和膠粘劑等。
      As an intermediate of organic synthesis, tetrahydrophthalic anhydride can be used to produce pesticides such as chlordane and chlordane, as well as plasticizers, epoxy resin curing agents, unsaturated polyester resins, solvent-free paints and adhesives.
