查询词典 methylaniline

Now reduction reaction with iron powder is the major method of preparing Methylaniline in domestic.But because it doesn't consist with requirement of environment protection, it has been banned.

该法存在操作条件差、成本高、消耗大量精铁粉、生产劳动强度大、生产条件恶劣、排出铁泥而污染环境等缺点。

The Mannich-type addition of O , O'-dialky phosphite to 2-fluorobenzaldehyde and 4-trifluoro- methylaniline was carried out in one pot by means of adopting three kinds of green synthetic methods, microwave irradiation, ionic liquid and free solvent-catalyst condition. According to the results, the synthetic method was optimized without catalyst and solvent at 100 ℃ and 15 min, and it was economic, convenient, high yields, timesaving and environment friendly.

采用微波辐射﹑离子液体和无溶剂无催化剂三种绿色合成方法，分别进行了以亚磷酸酯、邻氟苯甲醛和对三氟甲基苯胺为原料的类Mannich一锅法合成反应研究，经合成筛选，优选出控制反应温度100 ℃、无溶剂和无催化剂加热反应15 min的合成方法，实验结果表明该方法经济、简便、产率高、反应时间短及对环境友好。

Those who illegally hold more than 200 grams but less than 1,000 grams of opium or hold more than 10 grams of heroin but less than 50 grams of methylaniline or hold a large quantity of other drugs are to be sentenced to less than three years of fixed-term imprisonment or detention or control and, in addition, be sentenced to paying a fine.

Bone marrow-derived mesenchymal stem cells are capable of chondrogenesis, making them a possible source of cells for injectable cartilage tissue engineering. There exist different ideas on the ability of mesenchymal stem cells's chondrogenesis in monolayer culture. Because of this, the effect of adult rabbit's bone marrow-derived mesenchymal stem cells chondrogenesis in monolayer culture was studied. The mesenchymal stem cells was isolated from adult rabbit's bone marrow and monolayer cultured. TGF-β1, Vit-C and Dexamethasone were used. Immunohistochemistry analyses and histological staining of H-E, Methylaniline blue and Alcian blue were performed to identify the expression of collagen type Ⅱ and cartilage associated matrix. The results showed that the induced cells expressed and produced collagen type Ⅱ and cartilage associated matrix. This suggests that the differentiation of adult rabbit's marrow-derived mesenchymal stem cells into chondrocyte in monolayer culture is feasible and may be induced by TGF-β1, Vit-C and Dexamethasone.

骨髓基质干细胞的软骨分化潜能使其可能成为可注射组织工程化软骨研究的种子细胞，为探讨体外培养的骨髓基质干细胞在平面诱导条件下软骨分化的可行性，我们进行下列实验：获取并体外平面培养成体兔骨髓基质干细胞，应用TGF-β〓、Vit-C和地塞米松对其软骨分化诱导，诱导后的骨髓基质干细胞行细胞爬片组织学和Ⅱ型胶原免疫组化，结果证实，诱导后骨髓基质干细胞可分泌Ⅱ型胶原，组织学染色可见类似于软骨细胞，由此证明体外培养的骨髓基质干细胞在平面诱导条件下可以软骨分化，其软骨诱导因子为TGF-β〓、Vit-C和地塞米松。

Those who smuggle, traffic, transport or manufacture opium with a quantity less than 1,000 grams but more than 200 grams, those who smuggle, traffic, transport or manufacture heroin or methylaniline with a quantity less than 50 grams but more than 10 grams, and those who deal with other drugs in large quantity are to be sentenced to more than seven years of fixed-term imprisonment and, in addition, be sentenced to a fine.
