इंग्रजी मध्ये HYDROGEN FLUORIDE म्हणजे काय?
हायड्रोजन फ्लोराइड
हायड्रोजन फ्लोराईड हे सूत्र HF बरोबर एक रासायनिक संयुग आहे. हा रंगहीन वायु हा फ्लोरिनचा मुख्य औद्योगिक स्त्रोत आहे, बहुतेक हाइड्रोफ्लोरिक एसिडसारखा पाण्यासारखा स्वरूपात असतो आणि अशा प्रकारे फार्मास्यूटिकल आणि पॉलिमरसह अनेक महत्वाच्या संयुगेचा अग्रदूत आहे. एचएफचा वापर पेट्रोकेमिकल उद्योगात मोठ्या प्रमाणावर केला जातो आणि हे अनेक सुपरएसीडचे एक घटक आहे. हायड्रोजन फ्लोराइड खोलीचे तापमान खाली उकडते तर इतर हायड्रोजन हॅलिड्स खूपच कमी तापमानांवर होतात. अन्य हायड्रोजन हॅलिड्सच्या विपरीत, एचएफ हवेत पेक्षा अधिक हलक्या असून त्यास छिद्र पाडणार्या पदार्थांमुळे तुलनेने लवकर फरक पडत आहे. हायड्रोजन फ्लोराईड एक अत्यंत धोकादायक गॅस आहे, जो ऊतींचे संपर्कात राहून उपरोधिक आणि भेदक हायड्रोफ्लोरिक ऍसिड तयार करतो. कॉर्नियासचा जलद विनाशामुळे गॅस देखील अंधत्व होऊ शकतो. फ्रेंच रसायनशास्त्रज्ञ एडमंड फ्रेमी यांनी फ्लोरिन वेगळे करण्याचा प्रयत्न करताना निर्जल हायड्रोजन फ्लायराइड शोधल्याबद्दल श्रेय दिले आहे, तरीही कार्ल विल्हेम शेले यांनी 1771 मध्ये हायड्रोफ्लोरिक अॅसिड तयार केली होती, आणि हे ऍसिड नंतर काचेच्या उद्योगात परिचित होते.
इंग्रजी शब्दकोशातील hydrogen fluoride व्याख्या
शब्दकोशमध्ये हायड्रोजन फ्लोराईडची परिभाषा एक रंगहीन विषारी गंजणाची वा गॅस आहे जो कॅल्शियम फ्लोराईड आणि सल्फ्यूरिक ऍसिडच्या अभ्यासात बनलेली द्रव आहे: फ्लोरायंटिंग एजंट आणि उत्प्रेरक म्हणून वापरली जाते. फॉर्म्युला: एचएफ हायड्रोजन फ्लोराईडची इतर परिभाषा हा हायड्रोजन फ्लोराईडचा एक द्रवपदार्थ आहे; हायड्रोफ्लोरिक ऍसिड
