以前的順酐（馬來酸酐）樣子以粉末主導(dǎo)，由于馬來酸酐、具備嗆鼻和辣眼的味道，因此粉末對(duì)人的刺激性更大，并且量太低，因此慢慢被片狀順酐取代?，F(xiàn)階段還要制造粉末狀順酐的廠家基本上沒有，有都是作為高檔獨(dú)特顧客人群的商品在少量制造，不規(guī)模。
The former maleic anhydride (maleic anhydride) was dominated by powder. Due to the maleic anhydride, which has the smell of choking nose and hot eyes, the powder is more irritating to people, and the production is too low, so it is gradually replaced by flake maleic anhydride. At the present stage, there are basically no manufacturers who want to manufacture powdered maleic anhydride. There are only a small number of products manufactured as high-end and unique customer groups, which are not large-scale.
片狀順酐（馬來酸酐）由于流水線的切割刀鋼度較為強(qiáng)，而順酐自身是結(jié)晶，因此所切的片的樣子沒辦法操縱，沒辦法保證勻稱，會(huì)有許多粉末造成，封進(jìn)包裝袋子后，商品一受潮，一擠壓成型，還是非常容易粘成塊狀，導(dǎo)致加料的不便捷，并且量上提不上，落伍的加工工藝淘汰也不新奇了。
Not to mention, out of date processing technology is not new.
受原材料苯的上漲，各地域剛開始挺價(jià)實(shí)際操作，苯法加工廠受原材料上漲危害團(tuán)體上漲，并且廉價(jià)貨慢慢得勢(shì)，持貨商沒有響應(yīng)積極主動(dòng)，廉價(jià)出不來，援手主要加工廠，但是受中下游產(chǎn)銷率不夠危害，預(yù)估上漲力度不容易很大，等主要加工廠出具體指導(dǎo)價(jià)錢。
