甲醇上游产品

甲醇下游产品

1.工业上合成甲醇几乎全部采用一氧化碳加压催化加氢的方法，工艺过程包括造气、合成净化、甲醇合成和粗甲醇精馏等工序。粗甲醇的净化过程包括精馏和化学处理。化学处理主要用碱破坏在精馏过程中难以分离的杂质，并调节pH值；精馏主要是脱除易挥发组分如二甲醚，以及难挥发组分职乙醇、高碳醇和水。粗馏后的纯度一般都可达到98%以上。

2.将工业甲醇用精馏的方法将含水量降到0.01%以下。再用次碘酸钠处理，可除去其中的丙酮。经精馏得纯品甲醇。

3.BV-Ⅲ级甲醇的制备主要采用精馏工艺。以工业甲醇为原料，经精馏、超净过滤、超净分装，得高纯甲醇产品。

4.一般均以工业甲醇为原料，经常压蒸馏除去水分，控制塔顶64～65℃，过滤除去不溶物即可。

甲醇密度是多少？甲醇一升等于多少公斤？

2019-07-23 22:32:50

甲醇密度为0.79 g/cm³，1L=1000mL=1000cm³。根据密度公式：质量=密度×体积=0.79 g/cm³×1000cm³=790g=0.79kg，所以甲醇一升的质量是0.79公斤。另外85%甲醇的温度，密度对照表如下：0℃ 85%甲醇密度851.0kg/m310℃ 85%甲醇密度8...
