1.主要用于生產不飽和聚酯樹脂、醇酸樹脂、農藥馬拉硫磷、低毒農藥4049、長效碘胺的原料。也是涂料、馬來松香、聚馬來酐、順酐-苯乙烯共聚物。也是生產油墨助劑、造紙助劑、增塑劑和酒石酸、富馬酸、四氫呋喃等的有機化工原料。用作環氧樹脂的固化,在有機合成中可用于制造丁二酸、丁二酸酐等。在醫藥工業中用作制造長效磺胺等藥物。食品工業中用于制造酸味劑蘋果酸及酒石酸等。
1. It is mainly used in the production of unsaturated polyester resin, alkyd resin, malathion, 4049 and long-acting iodamine. It is also coating, maleic rosin, polymaleic anhydride, maleic anhydride styrene copolymer. It is also an organic chemical raw material for the production of ink additives, paper additives, plasticizers and tartaric acid, fumaric acid, tetrahydrofuran, etc. It can be used as curing agent of epoxy resin, succinic acid and succinic anhydride in organic synthesis. In the pharmaceutical industry, it is used to manufacture long-acting sulfonamides and other drugs. In the food industry, it is used to make sour agents such as malic acid and tartaric acid.
用作環氧樹脂的固化劑。本品是重要的基本有機原料之一,主要用于制不飽和聚酯樹脂、醇酸樹脂、尼龍-4等,也是生產紙張處理劑、膠黏劑、油墨、油漆、殺菌劑、除草劑、殺蟲劑、植物生長調節劑的主要原料。
Used as curing agent of epoxy resin. This product is one of the important basic organic raw materials. It is mainly used for making unsaturated polyester resin, alkyd resin, nylon-4, etc. it is also the main raw material for producing paper treatment agent, adhesive, ink, paint, bactericide, herbicide, insecticide, plant growth regulator.
2.測定具有共軛雙鍵有機化合物的試劑。也用于合成樹脂、涂料、農藥、醫藥、食品、及潤滑油添加劑等。
2. Reagents for the determination of conjugated double bond organic compounds. It is also used in synthetic resin, coating, pesticide, medicine, food, lubricating oil additive, etc.
3.用于有機合成,合成纖維中間體。用作分析試劑,如測定具有共軛雙鍵有機化合物的試劑。
3. Used in organic synthesis, synthetic fiber intermediates. Used as an analytical reagent, such as for the determination of organic compounds with conjugated double bonds.
4.用作環氧樹脂的固化劑,參考用量19~27質量份,因反應性和揮發性大,不宜單獨使用,多與他酸酐或增韌劑(如均苯四酸二酐)混熔使用。固化條件160~200℃/(2~4h)。也可用于與EVA和PE共混物接枝,制備熱熔膠新型聚合物,提高黏合力。
4. As curing agent of epoxy resin, the reference dosage is 19-27 phr. Because of high reactivity and volatility, it is not suitable to be used alone. It is often mixed with other anhydride or toughening agent (such as pyromellitic dianhydride). The curing conditions were 160-200 ℃ (2-4h). It can also be used to graft EVA and PE blends to prepare new hot melt adhesive polymers and improve the adhesion.
還可用作生產丙烯酸酯乳液的改性單體及與SBS接枝。在有機合成中可用于制造丁二酸、丁二酸酐、γ-丁內酯、四氫呋喃、丁二酰亞胺、丁二酰氯、不飽和聚酯樹脂、順丁烯二酸二丁酯(增塑劑)等產品。農藥工業中用于制造馬拉硫磷、馬來酰肼及殺菌劑、除草劑等。在醫藥工業中用于制造長效磺胺、氨茶堿等藥物。食品工業中用于制造酸味劑蘋果酸及酒石酸等。還用作造紙施膠劑、潤滑油降凝劑、水質穩定劑、油墨添加劑、織物柔軟整理劑及用于制造表面活性劑等。
It can also be used as a modified monomer for the production of acrylate emulsion and grafting with SBS. In organic synthesis, it can be used to produce succinic acid, succinic anhydride, γ - butyrolactone, tetrahydrofuran, succinimide, succinyl chloride, unsaturated polyester resin, dibutyl maleate (Plasticizer) and other products. In pesticide industry, malathion, maleic hydrazide, fungicide and herbicide are used. In the pharmaceutical industry, it is used to manufacture long-acting sulfanilamide, aminophylline and other drugs. In the food industry, it is used to make sour agents such as malic acid and tartaric acid. It is also used as paper sizing agent, lubricating oil pour point depressant, water quality stabilizer, ink additive, fabric softening agent and surfactant.
