1) cold alkali purification
冷碱净化，冷碱抽提
2) reinforced alkaline extraction
碱抽提强化
1.
The technique of reinforced alkaline extraction was used to improve the bleaching efficiency of kraft reed pulp.
系统地研究了硫酸盐苇浆碱抽提强化的工艺及其规律。
4) alkaline extraction
碱抽提
1.
The results showed that little xylan absorbed on fiber or carbohydrate linked to cellulose was removed out during xylanase pretreatment stage and these carbohydrate mainly were removed out during alkaline extraction stage, and this would lead to an obvious decrease in special absorption coefficient.
结果表明,木聚糖酶处理过程很少脱除吸附在纤维表面或是联接在纤维表面的碳水化合物,而在碱抽提过程中,这些与木聚糖酶的反应产物才真正脱离,光吸收系数也有明显降低。
2.
The effects of xylanase AU-PE89 treatment combined with chelating and alkaline extraction on HD bleaching of NaOH-AQ wheat straw pulp, was investigated.
结果表明:木聚糖酶结合螯合处理和碱抽提可以有效改善NaOH-AQ麦草浆HD漂白效果,同时还可以降低HD漂白废液的CODCr,减少漂白污染。
5) caustic extraction
碱液抽提
1.
Mercaptans in the light fractions of FCC naphtha from different refineries were removed by caustic extraction.
采用碱液抽提的方式,对来自不同炼油厂的催化裂化汽油轻馏分进行了脱硫醇精制试验。
2.
The trimethylsilyl(TMS) derivatives of phenolic compounds,concentrated from the oil through high efficiency caustic extraction method,were prepared by reacting quantitatively with derivative reagent.
使用高效碱液抽提法富集煤液化油中酚类组分,并使用衍生化试剂与该组分定量反应,得到挥发性大幅提高、化合物间分离程度显著改善、适于定性定量分析的酚类硅醚化衍生物。
6) hot alkali extraction

补充资料：冷碱法纸浆
分子式：
CAS号：
性质：用稀碱液在室温下对木片或草片进行自然浸渍或加压浸渍，同时或浸渍后进行机械处理分离纤维，纸浆得率可达85％～94％。此法原料适应性强，可使用各种不同的纤维材料，以阔叶木最为适宜。本色冷碱法化学机械浆可抄造瓦楞原纸。漂白冷碱法化学机械浆与磨木浆、化学浆可配抄新闻纸等。
