In production, the ratio of acetylene to hydrogen chloride is required such that acetylene is not in excess, while hydrogen chloride is present in excess (2-10%)
(Acetylene) not in excess, hydrogen chloride (5-10% in excess)
The ratio requirement for acetylene and hydrogen chloride in production is that hydrogen chloride is in excess; acetylene is not in excess, with hydrogen chloride making up 2~10% of the mixture.
Acetylene. . . . . . . . . . . . . ?
The ratio requirements for acetylene and hydrogen chloride in production are such that hydrogen chloride is in excess, while acetylene is not; the excess amount of hydrogen chloride is specified to be 2–10%.
In production, the ratio of acetylene to hydrogen chloride requires that acetylene be not in excess, while hydrogen chloride should be in excess by (2-10%).
In production, the ratio of acetylene to hydrogen chloride requires that acetylene be not in excess, while hydrogen chloride should be in excess by (2-10%).
