石油绝缘沥青可作为油气管线绝缘材料,但由于其产量不能满足需要,故仍要采用少量石油建筑沥青作为管线的绝缘材料。全苏石油产品储运及应用科学研究所同新乌发石油加工厂共同进行了研究,以寻找适合作为石油绝缘沥青的原料来源。研究结果表明,热裂化装置减压渣油能够成为这种原料的有前途的来源之一。 相似文献

The present investigation revealed the potential benefits of nanofiltration application in herbal extracts processing. Nanofiltrations of modelling solution of caffeic and rosmarinic acid in ethanol and ethanolic rosemary extract were carried out in a laboratory cross-flow system. Duramem™ 200 nanofiltration membrane was selected based on screening experiments. The experimental data and model predictions demonstrated the efficacy of a semi-batch cross-flow diafiltration process for concentration of fresh rosemary extracts. The observed absence of significant loss of antioxidant capacity in the retentate during the process and the degree of extract concentration achieved may allow retentate direct application as preservative and functional ingredient in the foods, cosmetics, neutraceuticals and medicines. The capability of the selected membrane to separate monophenolic acids from higher molecular weight antioxidant compounds in the extracts was also discussed. The dry solids content in the permeate was found sufficiently low as to permit its direct re-use in the extraction process thus bringing additional economical benefits. 相似文献

Walnut green husk is one of the main waste products from walnut and could be used as a source of natural dyeing compounds such as juglone. The present study was conducted to evaluate the effective use of walnut green husk extract as a natural hair dye. Dyeing properties, fastness and antimicrobial behaviours of dyed hair and also a skin irritation test for natural hair dye on rat skin were examined. When the extract was mixed with ascorbic acid as a developer, ferrous sulphate as a mordant, and Aloe vera extract used as a secondary mordant and also a cosmetic ingredient, the reaction resulted in a dark‐brown colour on hair samples. The dyed hair exhibited appropriate colour strength having excellent morphology for a hair surface coated with dye molecules. In addition, the dyed hair possessed good resistance to washing and daylight fastness, without any irritant properties as shown in a rat model, although high concentrations of iron‐based mordant may be problematic for long‐term usage. This paper also suggests the use of natural mordants such as lactic and oxalic acids to avoid any probable risks. Walnut green husk extract was an appropriate natural hair dyeing agent in practice and showed maximum antimicrobial activity compared with semi‐synthetic and commercial hair dyes. The results demonstrated that walnut green husk can be used as an economical, valuable, eco‐friendly and safe source of dyeing and antimicrobial agents for cosmetic products. 相似文献

不同工艺制得玫瑰精油香气差异对比分析 总被引:1,自引:0,他引:1
采用水蒸气蒸馏法、溶剂萃取法、超临界CO2萃取法提取玫瑰精油,采用气质联用技术对精油进行成分分析,结果表明,超临界CO2萃取法得到的玫瑰精油共有56种成分,以高级醇类和酯类为主,其中酯类相对质量分数是3种方法中最高的,为13%,特征清香成分相对质量分数为4.568%,总体上香气甜而饱满,拥有厚重优雅的底香,油脂味很淡,清香气息相对突出;水蒸气蒸馏工艺玫瑰精油含有60种成分,以高级醇类为主要成分,相对质量分数高达74.492%,主体香气成分相对质量分数最高,为72.057%,但苯乙醇的相对质量分数却只有0.711%,气息虽然香甜,但略显单薄,缺少蜜样香气;溶剂萃取玫瑰精油含有48种成分,以高级醇类和酯类为主要成分,烷酮类的相对质量分数较高,达到4.257%,所以油脂味较重,清香气息不突出,天然感较差. 相似文献
