氯化(hua)氫的(de)制備(bei)方(fang)法(fa)中(zhong)，最(zui)常用的(de)是合成法(fa)，合成法(fa)制備(bei)氯化(hua)氫工藝(yi)在眾多制備(bei)方(fang)法(fa)中(zhong)技術最(zui)為成熟。具體操作(zuo)步驟流(liu)程如下：

    根據氫(qing)(qing)(qing)氣(qi)(qi)與氯(lv)(lv)(lv)(lv)氣(qi)(qi)反應(ying)(ying)方程(cheng)式，兩者理論是按照1﹕1分(fen)子比(bi)(bi)合(he)成(cheng)(cheng)的，但(dan)工(gong)業(ye)上(shang)都是控(kong)(kong)制氫(qing)(qing)(qing)氣(qi)(qi)過量的。一般在氯(lv)(lv)(lv)(lv)化氫(qing)(qing)(qing)合(he)成(cheng)(cheng)中(zhong)控(kong)(kong)制分(fen)子比(bi)(bi)為(wei)氫(qing)(qing)(qing)氣(qi)(qi)﹕氯(lv)(lv)(lv)(lv)氣(qi)(qi)=（1.05～1.1）。在合(he)成(cheng)(cheng)鹽酸的合(he)成(cheng)(cheng)爐中(zhong)，氫(qing)(qing)(qing)氣(qi)(qi)過量還多些。氫(qing)(qing)(qing)氣(qi)(qi)過量最多不能(neng)超過10%，不然會造成(cheng)(cheng)產(chan)(chan)品氯(lv)(lv)(lv)(lv)化氫(qing)(qing)(qing)純(chun)度下降，乃至影響氯(lv)(lv)(lv)(lv)乙(yi)烯收率。而氫(qing)(qing)(qing)氣(qi)(qi)過量超過20%則(ze)有可能(neng)形(xing)成(cheng)(cheng)爆炸混合(he)物(wu)，不利于安全生(sheng)(sheng)產(chan)(chan)。 但(dan)如果氯(lv)(lv)(lv)(lv)氣(qi)(qi)過量，則(ze)游(you)離(li)(li)氯(lv)(lv)(lv)(lv)易(yi)與爐壁以及冷卻(que)管等反應(ying)(ying)生(sheng)(sheng)成(cheng)(cheng)黃色結晶氯(lv)(lv)(lv)(lv)化鐵而腐蝕設(she)備(bei)。游(you)離(li)(li)氯(lv)(lv)(lv)(lv)還將(jiang)在降膜式吸收塔中(zhong)與水(shui)反應(ying)(ying)生(sheng)(sheng)成(cheng)(cheng)次氯(lv)(lv)(lv)(lv)酸，對(dui)不透(tou)性石墨(mo)起緩慢(man)的局部(bu)氧化作用。即使少量的游(you)離(li)(li)氯(lv)(lv)(lv)(lv)，也將(jiang)在氯(lv)(lv)(lv)(lv)乙(yi)烯合(he)成(cheng)(cheng)的混合(he)器中(zhong)與乙(yi)炔發生(sheng)(sheng)氣(qi)(qi)相(xiang)反應(ying)(ying)，生(sheng)(sheng)成(cheng)(cheng)極易(yi)爆炸的氯(lv)(lv)(lv)(lv)乙(yi)炔，造成(cheng)(cheng)氯(lv)(lv)(lv)(lv)乙(yi)烯合(he)成(cheng)(cheng)系(xi)統的爆炸。因此，為(wei)杜絕氯(lv)(lv)(lv)(lv)化氫(qing)(qing)(qing)中(zhong)產(chan)(chan)生(sheng)(sheng)游(you)離(li)(li)氯(lv)(lv)(lv)(lv)，合(he)成(cheng)(cheng)反應(ying)(ying)中(zhong)嚴格控(kong)(kong)制氫(qing)(qing)(qing)氣(qi)(qi)過量并控(kong)(kong)制在5—10%，并隨時注意氯(lv)(lv)(lv)(lv)、氫(qing)(qing)(qing)流(liu)量和視鏡中(zhong)燃燒(shao)火焰的顏色變化。
